CS2 Case Hardened Guide 2026: Blue Gem vs Gold Gem Patterns Explained
Mastering CS2's Most Complex Pattern System
Case Hardened is CS2's most pattern-dependent finish, where two identical weapons can differ by $100,000+ based solely on pattern seed. A Karambit Case Hardened with pattern #387 "Ocean Blue" sells for $150,000-$300,000, while pattern #30 might be worth $2,000—identical knives, 15,000% price difference. This comprehensive guide covers the pattern seed system (0-1000), blue gem tiers, gold gem patterns, purple/blaze variants, weapon-specific tier lists, visual identification techniques, float value interactions, and investment strategies. Use our CS2 Float Checker to instantly identify pattern seeds and never miss an underpriced blue gem again.
What is the Case Hardened Finish?
Case Hardened is a weapon finish in CS2 that mimics the appearance of metal hardening processes, creating a random distribution of blue, purple, and gold colors across the weapon surface. Unlike most CS2 skins where patterns have minimal visual differences, Case Hardened patterns create dramatically different appearances that can multiply value by 10x-100x depending on color distribution.
The finish originated in CS:GO in the Arms Deal update (2013) and has become the most collectible pattern-dependent skin in Counter-Strike history. Case Hardened appears on numerous weapons including the legendary AK-47, all knife types, Five-SeveN, Galil AR, MAC-10, P250, and more. Each Case Hardened skin has a unique pattern determined by its pattern seed number (also called pattern index or pattern ID).
What makes Case Hardened unique is the community-assigned value hierarchy: blue is most valuable (rarest and most visually striking), purple is mid-tier, and gold is least valuable (most common). This color preference has created an entire sub-market of "blue gem" collecting where pattern seeds showing 90%+ blue coverage command six-figure prices on premium weapons. Understanding Case Hardened patterns is essential for advanced CS2 trading and collecting.
Understanding the Pattern Seed System (0-1000)
Every Case Hardened skin is assigned a pattern seed number from 0 to 1000 when created (1,001 possible patterns total). This pattern seed determines where the blue, purple, and gold texture is mapped onto the weapon model. Pattern seeds are permanent and never change—they're as fundamental to the skin's identity as its float value.
How Pattern Seeds Work
Pattern Assignment
When you unbox, trade up for, or receive a Case Hardened skin, the game randomly assigns a pattern seed from 0-1000. Each seed maps the texture differently onto the weapon model. For example, pattern #661 places the blue section of the texture on the AK-47's magazine and body, while pattern #179 places it differently, creating distinct appearances.
Same Seed, Different Weapons
Pattern #661 looks completely different on an AK-47 (legendary blue gem) versus a Five-SeveN (mediocre pattern) because each weapon model has different surface geometry. A "god-tier" pattern for one weapon might be worthless on another. Pattern knowledge is weapon-specific.
Pattern Permanence
Pattern seeds cannot be changed, removed, or modified. The pattern assigned when the skin was created stays with it forever. This creates scarcity—only a finite number of each pattern exists for each weapon. Our CS2 Float Checker displays pattern seeds instantly so you can verify patterns before purchase.
Pattern Rarity
All pattern seeds (0-1000) have equal probability when skins are created—pattern #661 is just as likely as pattern #30. However, because 90%+ of patterns show majority gold (low value), the minority showing majority blue (high value) become extremely valuable due to demand vastly exceeding supply.
Key Insight: Value comes from demand, not rarity. All patterns are equally rare, but blue patterns are exponentially more desired.
Blue Gems: The Crown Jewels of Case Hardened
Blue gems are Case Hardened patterns with exceptionally high blue coverage on the playside (the visible side when holding the weapon). The term "blue gem" originated from the CS:GO community and specifically refers to patterns where blue is the dominant color—typically 70%+ blue coverage, with 85-100% being considered true premium blue gems.
Blue gems represent the pinnacle of Case Hardened collecting. The most famous blue gem patterns have legendary status: AK-47 #661 "Scar Pattern," Karambit #387 "Ocean Blue," Karambit #670, Five-SeveN #321 "Full Blue," and Five-SeveN #278. These patterns are instantly recognizable to collectors and have established track records of appreciation, with some individual skins appreciating 500-2000% over 5-10 years.
Complete Blue Gem Tier System
Tier 1 - God Tier Blue Gems
Near-perfect or perfect blue coverage with minimal to zero purple/gold. These are investment-grade assets with proven long-term appreciation (15-30% annually). Extremely illiquid—expect 3-12 months to sell at full value. Only for serious collectors with $20,000+ budgets.
Legendary Tier 1 Patterns by Weapon:
AK-47 #661 "Scar Pattern"
95% playside blue with distinctive scar marking | FN: $80,000-$150,000+ | MW: $40,000-$80,000
Most iconic AK blue gem, instantly recognizable worldwide
AK-47 #670 "Honorable Mention"
92-94% playside blue | FN: $50,000-$100,000 | MW: $25,000-$50,000
Second most famous AK pattern, excellent investment alternative to #661
AK-47 #387 "Blue Magazine"

Stunning full blue slide, most liquid Five-SeveN Tier 1
Five-SeveN #868 "Blue Dream"
95-97% playside blue | FN: $10,000-$25,000 | MW: $5,000-$13,000
Clean blue pattern, excellent budget Tier 1 entry point
Tier 2 - High-Tier Blue Gems
Excellent blue coverage with small purple/gold elements. Still considered premium blue gems with strong collector demand. Better liquidity than Tier 1 (1-3 months to sell). Best balance of prestige and tradability for collectors with $3,000-$50,000 budgets.
Value Ranges by Weapon (Factory New):
- • Karambit: $20,000-$80,000 (pattern-dependent, #151, #809, #463)
- • M9 Bayonet: $15,000-$50,000 (#417, #494, #868)
- • Butterfly Knife: $10,000-$40,000 (#782, #555, #828)
- • AK-47: $5,000-$25,000 (#179, #555, #321, #868)
- • Five-SeveN: $3,000-$12,000 (#690, #617, #592, #532)
Tier 3 - Mid-Tier Blue Gems
Good blue coverage but noticeable purple/gold elements. Entry-level blue gems for new collectors. Good appreciation potential (30-80% over 1-2 years) with reasonable liquidity (2-8 weeks). Ideal for beginners with $300-$5,000 budgets.
Value Ranges (Factory New):
- • Karambit: $3,000-$15,000
- • AK-47: $800-$4,000
- • Five-SeveN: $400-$2,000
- • Butterfly Knife: $2,500-$8,000
- • Galil AR: $150-$800
Tier 4 - Low Blue / Standard Patterns
Below 70% BlueMajority gold/purple with some blue elements. Not generally considered true "blue gems." Limited premium over standard Case Hardened prices (0-30%). Most Case Hardened skins fall into this category.
Gold Gems: The Reverse Value Proposition
While blue gems dominate Case Hardened collecting, a niche market exists for "gold gems"—patterns with 90%+ gold coverage and minimal blue. Gold gems represent the opposite extreme of the pattern spectrum. For most weapons, gold gems command discounts or zero premium compared to standard patterns. However, for specific skins, particularly certain knives, collectors appreciate the rarity of pure gold patterns.
Gold Gem Market Dynamics
Gold gems are a contrarian investment play. While 95% of collectors seek blue, a small group appreciates the clean, uniform appearance of full gold patterns. This niche market is growing as more traders recognize the aesthetic appeal of well-executed gold gems.
Gold Gem Valuation
- • Perfect Gold Gems (95%+ gold, no blue): 10-40% premium over standard CH on select knives
- • Clean Gold (85-95% gold): 0-20% premium, primarily on Karambit and M9 Bayonet
- • Mixed Gold (70-85% gold): Standard CH price, no premium
Reality Check: Gold gems are exponentially less valuable than blue gems. A Karambit blue gem worth $150,000 might have a gold gem equivalent worth $2,500-$3,500 (40% premium over $2,000 base). Gold gems are budget alternatives, not investment pieces.
Notable Gold Gem Patterns
- • Pattern #28: Nearly full gold on many weapons, clean appearance
- • Pattern #426: Gold-dominant with minimal blue/purple interference
- • Pattern #74: Popular gold pattern on Karambit specifically
Note: Gold gem patterns are not as rigorously documented as blue gems. Verification tools and databases primarily focus on blue coverage.
Gold Gem Investment Considerations
Gold gems have limited appreciation potential compared to blue gems. They're best purchased at or near standard Case Hardened prices for personal use, not investment. The market is illiquid—even perfect gold gems can take months to sell. Only pursue gold gems if you genuinely appreciate the aesthetic, not for profit potential.
Purple and Blaze Patterns: The Middle Ground
Between blue gems and gold gems lie purple-dominant patterns and "blaze" patterns (purple-blue-gold mix creating fiery appearance). These represent the vast majority of Case Hardened skins and typically command little to no premium over standard prices. However, certain purple or blaze patterns have niche collector appeal, particularly when they create unique visual effects.
Purple and Blaze Pattern Characteristics
Purple-Dominant Patterns (50%+ Purple)
Purple is the "transition" color between blue and gold in the Case Hardened texture. Purple-heavy patterns typically command 0-15% premiums. On knives with excellent purple distribution and minimal gold, some collectors pay 20-30% premiums, but this market is very niche. Best purchased at standard prices.
Blaze Patterns (Mixed Blue/Purple/Gold)
"Blaze" refers to patterns where all three colors mix in fiery, flame-like patterns. Some collectors appreciate well-executed blaze patterns for their visual complexity. However, the market is minimal—most blazes sell at standard CH prices. Avoid paying premiums unless you personally love the pattern.
Investment Verdict
Purple and blaze patterns are not investment-grade. They're personal preference items. If you're trading Case Hardened for profit, focus exclusively on Tier 1-3 blue gems. Purple/blaze patterns have minimal appreciation potential and poor liquidity even at fair prices.
Pattern Tier Lists by Weapon
Pattern value is weapon-specific. A legendary pattern for AK-47 might be mediocre on Five-SeveN. Here are comprehensive tier lists for the most popular Case Hardened weapons:
AK-47 Case Hardened
Most popular Case Hardened weapon. Pattern #661 is the holy grail. Good liquidity across all tiers.
Tier 1 Patterns (FN: $35,000-$150,000+)

#387, #321, #670, #868, #278, #592
Perfect For: Learning blue gem trading, building diversified portfolios, quick flips.
Price Differences: Understanding the 100x Premium
The price gap between standard Case Hardened patterns and top-tier blue gems is staggering—often 50x-100x base price. A standard Karambit Case Hardened Factory New sells for $1,800-$2,500, while a Karambit #387 blue gem Factory New sells for $150,000-$300,000. That's a 10,000% price difference for the same base skin with different pattern seeds.

Why This Creates Massive Trading Opportunities
Most sellers don't check pattern seeds. They list blue gems at standard Case Hardened prices, creating opportunities to buy $50,000 skins for $500. Use our CS2 Float Checker to scan marketplace listings for pattern seeds instantly. Even finding one underpriced Tier 2 blue gem per month generates $5,000-$15,000 profit.
How to Identify Patterns Visually
While pattern databases and tools are essential for verification, experienced collectors can estimate blue gem tier visually. Developing pattern recognition skills accelerates marketplace scanning and helps you identify opportunities instantly without checking every pattern seed.
Visual Pattern Identification Techniques
Technique 1: Blue Coverage Estimation
Train your eye to estimate blue coverage percentage by comparing screenshots to known patterns. Start with obvious examples: 100% blue (Tier 1), 50% blue (mid-tier), 10% blue (standard). Build a mental reference library of patterns at 70%, 80%, 90%, and 95% blue. With practice, you can estimate blue % within 5-10% accuracy.
Accuracy: Medium-High | Speed: 1-3 seconds | Best For: Quick screening
Technique 2: Weapon-Specific Landmarks
Each weapon has "landmark" areas that indicate pattern quality. For AK-47, check magazine blue (critical) and body blue. For Karambit, check blade tip and edge. For Five-SeveN, check slide top. Learn which areas matter most for each weapon and scan those first.
Accuracy: High | Speed: 2-5 seconds | Best For: Familiar weapons
Technique 3: Color Distribution Patterns
Blue gems have characteristic "looks." Tier 1 blue gems appear uniformly blue with clean, solid coverage. Tier 3 blue gems have "streaky" blue with obvious gold/purple interruptions. Tier 2 is between—mostly blue with small distinct non-blue sections. Train pattern recognition by reviewing tier lists repeatedly.
Accuracy: Medium | Speed: Instant | Best For: Experienced traders
Technique 4: Tool-Assisted Verification
Don't rely on visual estimation for purchase decisions. After identifying a potential blue gem visually, use our CS2 Float Checker to see the exact pattern seed. Cross-reference with CSGOFloat Database to confirm tier and typical value. Never pay Tier 1 prices based on visuals alone.
Accuracy: Very High | Speed: 5-10 seconds | Best For: Purchase verification
Critical Verification Warning
Lighting in screenshots and marketplace previews varies dramatically. Patterns that look 90% blue in one lighting might be 70% blue in-game. Always verify pattern seed and inspect in-game before paying blue gem premiums. Screenshots can be manipulated. Pattern seeds cannot lie.
Investment Potential by Pattern Tier
Blue gem investment returns vary dramatically by tier, weapon, and holding period. Understanding investment characteristics by tier helps allocate capital appropriately and set realistic expectations for appreciation and liquidity.
Tier 1 Blue Gems: Long-Term Appreciation Plays
Tier 1 blue gems ($20,000-$300,000) are investment-grade collectibles comparable to fine art or rare watches. They appreciate steadily (15-30% annually historically) but are extremely illiquid. Suitable for 5-10 year holds with significant capital.
Historical Appreciation
15-30% / year
Typical Holding Period
3-10 years
Liquidity
Very Low
Time to Sell
3-12 months
Investment Strategy:
Buy Tier 1 blue gems only with capital you won't need for 3+ years. Focus on iconic patterns (#661 AK, #387 Karambit, #278 Five-SeveN) with established collector demand. Prioritize Factory New or low-float Minimal Wear. Expect to hold through market downturns. These are the "blue chip stocks" of CS2.
Tier 2 Blue Gems: Balanced Risk-Reward
Tier 2 blue gems ($2,000-$50,000) offer the best balance of appreciation potential and liquidity. They appreciate well (20-50% annually) while selling within weeks to months. Ideal for 1-3 year holds with moderate capital.
Historical Appreciation
20-50% / year
Typical Holding Period
1-3 years
Liquidity
Medium
Time to Sell
1-3 months
Investment Strategy:
Tier 2 is the "sweet spot" for most traders. Strong appreciation with acceptable liquidity. Focus on popular weapons (AK-47, Karambit, Five-SeveN, M9). Buy at fair market prices, hold 1-3 years, sell when demand peaks. These are growth investments with moderate risk.
Tier 3 Blue Gems: Quick Flips and Portfolio Diversity
Tier 3 blue gems ($200-$5,000) are entry-level investments with good liquidity. They appreciate moderately (30-80% over 1-2 years) and sell quickly (2-8 weeks). Perfect for beginners and quick flip strategies.
Appreciation (1-2 years)
30-80% total
Typical Holding Period
2-8 weeks
Liquidity
High
Time to Sell
2-8 weeks
Investment Strategy:
Tier 3 excels for learning blue gem trading, building diversified portfolios, and quick flips. Buy underpriced Tier 3 patterns on budget weapons (Galil, MAC-10, P250), hold briefly, resell at fair market. Low capital requirements reduce risk. High liquidity enables rapid turnover.
Float Value Considerations for Case Hardened
While patterns dominate Case Hardened valuation, float value still matters significantly. Blue gems combine pattern and float premiums multiplicatively, not additively—a Tier 1 blue gem with excellent float can be worth 30-50% more than the same pattern with mediocre float.
Float Value Impact on Blue Gem Pricing
Factory New (0.00-0.07): Premium Condition
Factory New is the primary condition for serious blue gem collecting. Within FN, lower floats command significant premiums:
- • 0.00-0.01 float: 20-40% premium over standard FN for Tier 1-2 blue gems
- • 0.01-0.03 float: 10-20% premium, still considered excellent
- • 0.03-0.05 float: Standard FN pricing, no premium
- • 0.05-0.07 float: 5-10% discount vs low-float FN
Investment Recommendation: Target 0.00-0.03 float for Tier 1-2 blue gems. The float premium pays for itself through faster sales and higher realized prices.
Minimal Wear (0.07-0.15): Best Value Condition
Minimal Wear blue gems offer excellent value—typically 40-60% discount vs Factory New for identical patterns. For budget-conscious collectors or weapons where wear is minimal (Karambit, M9), MW is ideal.
- • 0.07-0.10 float: Cleanest MW, minimal visual difference vs FN, 40-50% discount
- • 0.10-0.13 float: Standard MW, 50-60% discount vs FN
- • 0.13-0.15 float: Higher wear, 60-70% discount, still collectible
Investment Recommendation: MW is best for beginners and value-focused collectors. Target 0.07-0.10 float for premium weapons.
Field-Tested (0.15-0.38): Budget Blue Gems
Field-Tested blue gems are budget entry points, typically 70-80% discounts vs FN. However, liquidity is low and appreciation potential limited. Only recommended for Tier 1 patterns where even FT commands strong premiums.
Avoid FT for investment purposes unless buying iconic Tier 1 patterns at steep discounts.
Well-Worn / Battle-Scarred: Non-Investment Grade
Well-Worn (0.38-0.45) and Battle-Scarred (0.45-1.00) blue gems are extremely illiquid and have minimal appreciation potential. Even Tier 1 patterns struggle to sell. Only consider for personal use, never investment.
Do not invest in WW/BS blue gems. Liquidity is near-zero and demand minimal.
Frequently Asked Questions
What is the most valuable Case Hardened pattern in CS2?
Karambit Case Hardened pattern #387 "Ocean Blue" in Factory New with low float is the most valuable, selling for $150,000-$300,000+. The AK-47 pattern #661 "Scar Pattern" Factory New is second at $80,000-$150,000. Five-SeveN #278 "Skyblue" Factory New reaches $12,000-$28,000, making it the most valuable pistol blue gem.
How do I check the pattern seed of my Case Hardened skin?
Install our CS2 Float Checker Chrome extension to see pattern seeds instantly on marketplace listings and in your inventory. Alternatively, use CSGOFloat's item inspector by pasting the inspect link. Pattern seeds (also called pattern index or pattern ID) are displayed alongside float values.
Are gold gems worth investing in?
No, gold gems have minimal investment potential. While some collectors appreciate full gold patterns, the market is tiny and prices are near standard Case Hardened values. Gold gems on knives might command 10-40% premiums, but that's negligible compared to blue gems (50x-100x premiums). Invest in blue gems, not gold gems.
Is pattern #661 good on all weapons?
No, pattern #661 is legendary specifically for AK-47 where it creates the famous "Scar Pattern" blue gem. On other weapons like Five-SeveN or knives, pattern #661 might be mediocre or even low-tier. Pattern quality is entirely weapon-specific. A god-tier pattern for one weapon can be worthless on another.
Should I buy StatTrak Case Hardened blue gems?
StatTrak blue gems command 40-80% premiums over non-StatTrak versions but are significantly more illiquid. Only buy StatTrak if you plan to hold long-term (5+ years) or find deeply underpriced listings. For active trading, non-StatTrak is safer. StatTrak works best on AK-47 and popular knives where collector demand supports the premium.
How long does it take to sell a Tier 1 blue gem?
Tier 1 blue gems typically take 3-12 months to sell at full value. The buyer pool is extremely small—only elite collectors with $50,000+ budgets. To sell faster (1-2 months), expect to discount 20-30% below market value. Tier 2 blue gems sell in 1-3 months, Tier 3 in 2-8 weeks. Never invest in blue gems with capital you need within 12 months.
Can I find underpriced blue gems on Steam Market?
Yes, this is the primary strategy for blue gem traders. Most Steam Market sellers don't check pattern seeds and list blue gems at standard Case Hardened prices. Use our pattern seed checker to scan listings. Finding even one underpriced Tier 2 blue gem per month generates $5,000-$20,000 profit. Competition is increasing, so check listings frequently.
Do blue gems appreciate during market downturns?
High-tier blue gems (Tier 1-2) are relatively recession-resistant. They declined only 10-20% during the 2022-2023 CS:GO market crash while standard skins dropped 40-60%. Blue gems behave like collectible art—elite collectors accumulate during downturns. However, liquidity worsens during crashes. Tier 3 blue gems and budget weapons track the broader market more closely.
What's the best weapon for beginner blue gem collectors?
Five-SeveN Case Hardened is ideal for beginners. Tier 3 Five-SeveN blue gems cost $300-$1,500, making them accessible. The market is liquid with good demand. Patterns are easy to evaluate visually. Good appreciation potential (40-100% over 1-2 years). Once comfortable with Five-SeveN, expand to Galil AR, then AK-47, then knives as your budget grows.
Is backside blue important for knives?
Yes, backside blue matters for knives because you see both sides during inspect animations and gameplay. Knives with high blue on playside + backside command 15-40% premiums over playside-only blue gems. The premium increases with overall blue coverage—a double-sided 95% blue Karambit might be worth 30-40% more than a 95% playside-only version. Always check both sides before purchase.

Conclusion: Mastering the Case Hardened Market
Case Hardened patterns represent the most complex, rewarding, and profitable segment of CS2 trading. The combination of pattern rarity, visual appeal, and massive price differentials creates opportunities that casual traders never see. Understanding the pattern seed system (0-1000), memorizing tier lists, developing visual pattern recognition, and using verification tools transforms Case Hardened from confusing to extraordinarily profitable.
The blue gem market continues maturing, with increasing trader sophistication and growing collector demand. However, opportunities remain abundant for those who invest time in pattern education. Most sellers still don't check pattern seeds, particularly on budget weapons and international marketplaces. The rarest Tier 1 patterns remain concentrated among elite collectors, creating supply constraints that drive continuous appreciation.
Whether you're starting with Tier 3 Five-SeveN blue gems at $300 or investing in Tier 1 Karambit patterns at $150,000, the principles remain constant: verify patterns meticulously, understand weapon-specific tier lists, prioritize Factory New or clean Minimal Wear condition, buy at fair prices or underpriced listings, and hold premium patterns for long-term appreciation. Blue gems aren't just skins—they're investment vehicles, art pieces, and status symbols combined.
