Karambit Blue Gem: Patterns, Prices & Rarity Guide [2026]

The Karambit Blue Gem is the most expensive knife skin in Counter-Strike 2. In the game, 10 top tier patterns have enough blue on the playside to be considered true Blue Gems, placing the Karambit Blue Gem among the rarest skins available. These patterns are so rare that Blue Gem Karambits can reach tens of thousands of dollars, while Pattern 387 has been valued at up to $2 million. Based on these factors, the Karambit Case Hardened Blue Gem can be considered one of the most expensive items in Counter-Strike history.

Why Is the Blue Gem Karambit So Expensive?

Pattern Tier

Pattern tier is the main price factor for a Blue Gem Karambit in CS2. Case Hardened skins have around 1,000 possible pattern seeds, but only 158 Karambit patterns are classified as Blue Gem across all tiers. The tier depends on how much blue appears on the playside during inspection and gameplay. Higher-tier patterns have more blue coverage and fewer gold or gray areas on the visible blade. Pattern 387 is considered the God Tier seed, as it’s the only Karambit pattern with an almost fully blue playside and serves as the primary price benchmark for the Karambit Case Hardened Blue Gem.

Float Value

Float value affects how clean the blue areas of the knife appear in CS2. A lower float means less visible wear, a cleaner blade, and a higher price. Factory New condition is required for the highest price range, as collectors pay a premium for minimal wear on rare Blue Gem patterns. Float has a greater impact on Blue Gems than on many other finishes, as higher float values add a darker layer to the blade and reduce the clarity of the blue areas. As a result, the same pattern can vary significantly in market value depending on float.

Market Demand

The cases that can contain the Karambit Case Hardened are legacy containers that are no longer part of the active drop pool in CS2. Each opened legacy case permanently reduces the remaining supply that could produce a new Blue Gem Karambit. Collectors and investors focus on top playside Blue Gem patterns as new supply is extremely limited. As a result, Rare Karambit Blue Gems maintain strong demand even during slower skin market periods, as the supply of legacy cases continues to decline.

Chinese Community Impact

From 2017 to 2019, Chinese traders and collectors became more active in the CS:GO skin market, increasing demand for clean Blue Gem patterns. In Chinese collector circles, blue and gold are often associated with luck, wealth, and status, making Karambits with high blue coverage on the playside especially desirable. This demand has carried over into CS2, where full blue coverage on the visible side remains a key driver of value. The most notable example is Pattern 387, owned by the Chinese collector 青い王 (also known as Blue King or Newb Rage), who reportedly rejected a $1.5 million offer in 2021. This case helped establish the Blue Gem Karambit as a benchmark for the most valuable items in Counter-Strike.

Playside and Backside Blue Gem

In CS2, the playside is the side of the Karambit blade that players primarily see during inspection and gameplay, which makes it the key factor in determining the value of a Blue Gem. Case Hardened patterns are generated from a shared texture, which is why blue coverage can appear on different parts of the blade. The backside can sometimes have more blue coverage, but it doesn’t increase the price in the same way, as it’s not the main visible side in-game. A backside Blue Gem can cost around $3,000 to $5,000, while a play-side Tier 1 version can start at approximately $30,000. New buyers often mistake backside blue coverage for true play-side value.

Blue Gem Karambit Patterns: Full Tier List

Among roughly 1,000 possible Case Hardened patterns in CS2, only 158 Karambit seeds qualify as Blue Gems. The tier depends on how much blue appears on the playside. Pattern 387 has nearly 100% blue coverage on the playside, which is why it occupies the God Tier category on its own, with a separate price range.

The only known Factory New copy of Pattern 387 is owned by a Chinese collector. Patterns 442 and 269 are Tier 1 seeds, with about 80% blue coverage on the playside and prices ranging from $30,000 to $100,000+. Pattern 269 also features significantly more blue on the backside, making it more valuable for collectors who want strong coverage on both sides. Tier 4 represents the entry level for Blue Gem collecting in CS2, with prices starting at around $3,000 and reaching up to $10,000 for cleaner examples.

Notable Sales and Record Offers

The Blue Gem market largely operates outside public marketplaces, with most deals happening directly between collectors:

• In 2020, a 0.00 float Blue Gem sold for around $2,500 as a lower-tier example.
• In 2021, a low-float Blue Gem sold for more than $20,000 due to its pattern and float combination.
• In 2021, the owner of Pattern 387 rejected a $1.5 million offer. The knife is now valued at over $2 million.
• In June 2023, the Well-Worn Karambit #387 sold for around $120,000 on the secondary market.

Odds of Getting a Blue Gem Karambit

Obtaining a true Blue Gem Karambit in CS2 is extremely rare, as the result must pass through at least three stages, each significantly reducing the overall probability. Unboxing a Factory New Blue Gem #387 is even less realistic, with odds that are effectively close to zero.

Most collectors choose to buy a Blue Gem on the market rather than try to unbox one. The odds make direct purchase far more realistic than opening cases, especially for Pattern 387 or Factory New versions.

Which Cases Drop the Blue Gem Karambit?

The Karambit Case Hardened can drop from legacy CS2 containers released during the CS:GO era. These cases are no longer part of the regular Weekly Care Package drop pool. As a result, supply is limited to existing cases, old inventories, and secondary market listings. Each opened case permanently removes one potential container that could produce a new Blue Gem Karambit, which means the available supply continues to shrink over time.

How to Check Your Pattern Before Buying

In-Game Inspection

Open your CS2 inventory and select the skin you want to check. Right-click the item and choose Inspect. In the inspect window, click the i icon to open the item details. The pattern seed appears there as the Pattern Template. This method works for skins you already own.

Via Inspect Link on Steam Market

• Open the skin listing on the Steam Market.
• Right-click Inspect in Game and copy the link address.
• Copy the full inspect link that starts with steam://run/730/…
• Paste that link into a service like CSFloat.
• Check the exact pattern seed shown for that item.

Always check the pattern before buying. Compare the seed with the tier list to understand which tier the pattern belongs to and what the item is actually worth.
