The Karambit is one of the most iconic knives in CS2, and among its finishes, the Case Hardened Blue Gem stands at the top in terms of rarity, demand, and value. Unlike regular Case Hardened knives, a Blue Gem has almost full blue coverage on the blade, making it one of the most sought-after cosmetics in the entire game. Below is a detailed breakdown of what makes the Blue Gem Karambit special, how pattern seeds affect its appearance, and why it reaches record-breaking prices.
What Is a Blue Gem Karambit?
- The Case Hardened skin uses a randomized hardened metal texture applied to the knife’s blade.
- Each knife has a pattern seed (from 1 to 1,000) that determines how much of the blade is blue, gold, or purple.
- A Blue Gem is a pattern where the blade is almost fully blue on one or both sides.
- Collectors place the highest value on knives with solid blue play side coverage, since that’s the view seen most in-game.
Blue Gem Seed Patterns
Not all Case Hardened knives are equal. Out of 1,000 possible seeds, only a very small percentage produce true Blue Gem Karambits. These seeds are divided into tiers:
- Tier 1 – Near-full blue on the play side, minimal gold or purple.
- Tier 2 – Mostly blue but with small patches of gold/purple.
- Tier 3 – Partial blue highlights, not pure but still appealing.
For Karambits specifically, seeds like 387, 442, 442, 670, and 776 are among the most desirable because they produce near-full blue blades.
Market Value of Blue Gem Karambits
The price difference between a normal Case Hardened Karambit and a true Blue Gem is enormous:
- Regular Case Hardened Karambit: $300 – $800 (depending on wear).
- Tier 3 Blue Gem Karambit: $3,000 – $6,000.
- Tier 2 Blue Gem Karambit: $7,000 – $15,000.
- Tier 1 Blue Gem Karambit: $20,000 – $100,000+.
The highest recorded trades for Tier 1 Blue Gem Karambits exceed six figures, especially when combined with StatTrak or Factory New condition.
Condition and Float Value
- Factory New (0.00 – 0.07 float): Highest prices, cleanest appearance.
- Minimal Wear (0.07 – 0.15 float): Still premium, slightly cheaper than Factory New.
- Field-Tested and below: Blue coverage remains, but scratches reduce visual appeal. Value drops, though Blue Gem status still ensures a high price compared to regular Case Hardened.
