Karambit Case Hardened Blue Gem Seed Patterns

Did you know that a Karambit Case Hardened Blue Gem is the most expensive CS:GO skin ever? Currently valued at $1.5M, its value is expected to keep growing in the coming years thanks to its extremely rare seed pattern, making it the most exotic item in the game.


For many, this is the most beautiful item in CS:GO and CS2, and this is why we have created this guide, to cover the following points:

  • Define what is the Case Hardened finish and Blue Gem pattern
  • Explore all the Karambit Blue Gem seed patterns in existence
  • Check insights about the prices for a Karambit Blue Gem on the market
  • Bring answers to the most frequently asked questions about this skin and seed pattern


Let’s start by defining what the Case Hardened finish is, as well as the Blue Gem pattern, so you can understand what this skin is and how its price is being determined.

What is the Case Hardened Finish?

It is a finish provided to selected skins in a random way, consisting of blue, purple, dull gold and gray hues. In real life, the case hardened finish is accomplished by carburizing the metal surface, which is done by placing the object in a sealed steel container with active charcoal and then heating it up.


In CS:GO (CS2), this process is emulated by superimposing a square texture over the weapon, with a random pattern ranging from 1 to 1,000, successfully mimicking the method of action of the case-hardening process in real life.


Within this range we find 1,000 possible combinations of the blue, purple, dull gold and gray colors. However, skins collectors and players are mainly interested in the seed patterns with a high percentage of blue present, and such skins receive the name of Blue Gem, as in the case of the Karambit Case Hardened Blue Gem.


Now that it’s clear what the case-hardened finish is in CS:GO (CS2), let’s see what the Blue Gem pattern is.

What is the Blue Gem Karambit Seed Pattern?

It is one of the 161 patterns that have a predominant percentage of blue present, hence with minimal purple, dull gold and gray on the metal surface. And the more blue it is, the more valuable the Blue Gem seed pattern will be, as it’s the case for the rarest Karambit Blue Gem in existence, which is 99%+ blue, with just a small purple dot. 


Therefore, when it comes to the Karambit Case Hardened, it’s important to remark that not all patterns are Blue Gem. Over 80% of the seed patterns are standard, and they will not sell for a premium over the average market price.


Nonetheless, not all Blue Gem patterns are the same – as some are more valuable than others. You can find our full list of Karambit Case Hardened Blue Gem seed patterns below, properly organized in tiers.

List of Karambit Case Hardened Blue Gem Seed Patterns

Here you have all the available seed patterns of the Karambit Case Hardened that have been labeled as Blue Gem thanks to their high percentage of blue present on the metal surface.

Tier 1

Here you have all the seed patterns with the highest percentage of blue present – as high as 99%+ – making them the rarest and most valuable Karambit Blue Gems:


  • 387
  • 442
  • 269
  • 321
  • 73
  • 955
  • 853
  • 902
  • 507
  • 776


It is in this tier that we find the most valuable Karambit Blue Gem priced at $1,500,000 USD, which has the pattern 387. Completely ocean blue with a few dark spots and only one spot of purple, it has a percentage of 99%+ of blue present. These are the most expensive and rarest patterns.

Tier 2

Here you have the full list of Blue Gem seed patterns that belong to the Tier 2, because they have slightly less blue than the patterns from the top tier:


905, 698, 670, 130, 375, 664, 828, 74, 282, 453, 868, 377, 891, 798, 341, 541, 713, 661, 494, 4, 182, 823, 273, 838, 917, 82, 721, 510, 809, 470, 179


These seed patterns usually have a percentage of blue present that ranges from 80% to 90%, covering the vast majority of the metal surface, and this is why these Karambits can sell for a huge price tag, as they are extremely scarce.

Tier 3

Here you have all the Blue Gem seed patterns that belong to the Tier 3, due to their reduced percentage of blue present in comparison to the upper tiers:


262, 322, 30, 256, 139, 782, 989, 888, 11, 844, 92, 919, 112, 770, 330, 463, 306, 34, 429, 965, 811, 522, 803, 20, 575, 638, 914, 580, 236, 310, 916, 515, 631, 407, 371, 841, 555, 711, 632, 398, 598, 420, 283, 856, 202


The Karambit Case Hardened skins with these seed patterns are highly valuable as well, as they are extremely hard to find, just like any other Blue Gem Karambit.


For example, a Karambit Case Hardened with the pattern 30, with a float value of 0.036, will sell for approximately $5,000.

Tier 4

Finally, here you have all the Blue Gem seed patterns with the lowest percentage of blue present, hence they belong to the Tier 4:


25, 38, 335, 694, 424, 852, 849, 152, 727, 468, 106, 265, 194, 961, 138, 708, 942, 323, 325, 652, 749, 622, 334, 187, 974, 615, 405, 499, 432, 450, 643, 800, 381, 509, 426, 244, 935, 793, 913, 185, 945, 116, 434, 695, 151, 32, 177, 103, 588, 797, 401, 879, 839, 28, 497, 690, 363, 689, 875, 278, 775, 418, 259, 284, 595, 490, 286, 928, 985, 655, 953, 791


These are the less valuable Blue Gem Karambits, due to their reduced percentage of blue present. For example, a Blue Gem Karambit with the pattern 852, with a float value of 0.22, will sell for $2,000 to $2,500 USD.

Factors that Influence the Price of a Karambit Blue Gem
