This skin is the epitome of rarity and value, and is sought after for its breathtaking design. Its market value is outstanding, and with only a few existing true “Rank 1” patterns, it is ever more appealing. The Blue Gem Karambit goes beyond the term “skin.” It is a digital masterpiece and is a renowned trophy among collectors.
What is it about the Karambit that catches the eyes of the market? What factors contribute to some Blue Gems being sold for hundreds of thousands of dollars while others just hit the five-digit bracket? The most sought-after knife in the history of Counter-Strike comes with a unique rarity, pattern system, and a mythos that certainly deserves some attention.
What Is a Blue Gem Karambit?
A Karambit | Case Hardened knife in CS2 features a specific pattern known as a Blue Gem, and it is one of the rare patterns. The knife’s skin originates from the CS: GO weapon case, and it is covered in a case-hardened finish, which causes random colors to emerge on the blade, be it blue, gold, purple, or silver.
The majority of Case Hardened labeled knives exhibit a blend of colors, but deep blue vered its blade-dominated pattern is a hallmark of true Blue Gems. The value and rarity of the knife escalate with the uniformity of the blue.
The Role of Pattern IDs in Value
Each case-hardened skin in CS2 has a unique pattern ID that determines how the case-hardened colors appear on the weapon. Out of the 1,000+ patterns, only a few are considered “top-tier” Blue Gems—usually referred to as Rank 1 Blue Gems.
For the Karambit, pattern ID #387 is the most famous. It’s widely accepted as the absolute best Blue Gem pattern available. This specific ID displays a near-perfect blue hue across the play side of the blade, with minimal gold or silver interference.
Other high-ranking patterns (like #555, #321, or #44) are also considered valuable Blue Gems, though they may have slight gold or silver smudges on the edge or tip.
Just How Rare Is a Blue Gem Karambit?
The odds of unboxing a Karambit | Case Hardened are already extremely low—about 0.26% with a standard case opening. But the odds of getting a Blue Gem on top of that are even slimmer.
To understand the rarity, consider this:
- Only 1 in 1,000 pattern IDs is considered “top-tier.”
- Out of all Case Hardened Karambits, fewer than 10 true Rank 1 Blue Gems exist.
- Add in Factory New or Minimal Wear conditions, and the number drops even lower.
In short, owning a true Blue Gem Karambit is like holding a lottery ticket that hit the jackpot.
Real Market Value: What Are Blue Gem Karambits Worth?

- $30,000 – $80,000 for clean, high-blue patterns with good float
- $5,000 – $15,000 for partial Blue Gems with mixed colors

Many of these transactions happen off-market through high-end trading forums, trusted skin brokers, or skin investment groups.
