Karambit Blue Gem: The Most Expensive Knife in CS2 History

Everything is great about the CS2 knife Karambit Case Hardened Blue Gem! Its very form is amazing: the curved blade speaks of effective stealth aggression. The animation of a Karambit Knife is one of the best in Counter-Strike—the character spins the knife on their finger, using the special hole in the handle. And the Case Hardened skin with the Blue Gem pattern is simply a treasure for any CS2 inventory. It is impressively beautiful, so most players love it.

The rarity of this knife makes owning it a prestigious achievement and a promising investment for the skin trading business.

In a way, Karambit Blue Gem is a legendary knife. Collectors and gamers thoroughly study Blue Gem pattern variations to know for sure which has the biggest value. In this article on DMarket Blog, we explain everything about this CS2 knife skin, so you will be fully prepared for a potential purchase (or maybe even a profitable sale).

Let’s start with the basic definition.

What is a Blue Gem Karambit? It’s a Case Hardened skin for the CS2 Karambit Knife that covers the visible part of the blade with blue. If the whole blade is blue, it’s the best Blue Gem: the rarest and the most expensive.

The differences between Case Hardened skins exist because of the very process of creating them. The colorful pattern is a pretty big image. It recreates the process of hardening real-world metal, which causes the appearance of blue and yellow areas, surrounded by a grayish metallic background. The Karambit blade is placed over a random area of the pattern image—if it lies over the blue part, a Blue Gem is born, one of the best CS2 skins for Karambit. This process is automatic and random. Due to really small blue areas on the Case Hardened image, getting a totally blue Karambit blade is exceptional luck.

Karambit Case Hardened Blue Gem Patterns

There is one Blue Gem Karambit that is considered the purest pattern variation. It is the Karambit Case Hardened skin with pattern #387. It’s perfect! The person who owns such a knife is the collector Newb Rage (青い王) from China.

Thanks to the process of creating skins, there are significantly more Case Hardened Karambit patterns with the majority of blue on the blade. They have additions of other colors, though: yellow and gray. They are also considered Blue Gems, just of a lower tier. The bigger the areas of other colors, the lower the tier—and the skins are less rare and less expensive.

You absolutely need to know these patterns if you are seriously planning to buy a Karambit Blue Gem knife. The prices are super high, and it is better to check exactly what you are buying. No worries! We’ve got you covered. Take a look at the table below, and you will know the exact patterns for all Karambit Case Hardened Blue Gem skins.

Karambit Case Hardened Blue Gem in Trading

The rarity of Blue Gems makes these knives a very good investment for traders. The number of such skins is very limited, despite being around for more than 10 years. Getting one now should bring decent revenue in the future—that’s why the Chinese collector refused to sell their #387 pattern.

Still, lots of small aspects must be taken into account before really spending money on a Karambit Case Hardened Blue Gem.

• Check out the pattern number and the percentage of blue on the blade. Is this Case Hardened skin close to being a Blue Gem?
• Check out the float value. It should be low for high-cost knives.
• Use reliable platforms that guarantee secure transactions.
• Be careful with the price. Quite often, sellers make it too high for rare skins, so the investment loses any sense.

It is a good idea not to rush with such decisions. On DMarket, add to favorites the skins you are interested in, and then carefully look through your list to decide on the best offer.

The Role of Float Value

Another important factor to keep in mind is the float value. The range for Karambit Case Hardened skins is from 0.0 to 1.0, and this includes all possible variants:

• Factory New: from 0.0 to 0.7
• Minimal Wear: from 0.7 to 0.15
• Field-Tested: from 0.15 to 0.38
• Well-Worn: from 0.38 to 0.45
• Battle-Scarred: from 0.45 to 1.0

In general, the lower the value, the better the skin. Factory New and Minimal Wear are the most expensive. However, with Case Hardened, the amount of blue on the blade is more important. It would be better to have a Well-Worn knife of a tier 1 pattern than Minimal Wear but mainly gray.

The Karambit Blue Gem knives are some of the rarest and most expensive items in Counter-Strike. In addition to pure Blue Gem, there are four tiers of Case Hardened Karambits of specific patterns that are very close to being a perfect skin. Blue Gems may be good investments, but you need to consider a variety of factors before making a purchase. The chances of getting Karambit Blue Gem from a case are pretty low.
