The Karambit | Case Hardened is one of Counter-Strike’s most sought-after knives. Within this group, Blue Gem variants are the rarest and most valuable.
These patterns are defined by a high percentage of vivid blue on the play side of the blade. Collectors prize these knives for their aesthetic appeal and rarity, with the top-tier patterns often fetching astronomical prices.
In this guide, we break down all Blue Gem seed patterns into tiers based on how much blue the blade shows. We also provide a table summarizing available patterns for each tier.
Table of Contents
Tier 1 – True Blue Gem Karambits
Tier 1 patterns feature over 99% blue coverage on the play side. Gold and other colors are minimal or absent. These are the most desirable and valuable patterns.
Tier 2 – High-Coverage Blue Gems
Tier 2 patterns have slightly less blue than Tier 1, usually around 80–90% coverage. Small gold patches may appear, but the overall effect is still predominantly blue.
Tier 3 – Mid-Level Blue Gems
Tier 3 patterns show visible blue with gold or muted tones mixed in. They are less consistently dominant than Tier 2 but still qualify as Blue Gems.
Tier 4 – Lower Blue Gem Patterns
Tier 4 patterns have the least amount of blue coverage compared to other tiers. They often feature more gold and are generally less valuable, though still rarer than standard Case Hardened patterns.

A Blue Gem has a high percentage of vibrant blue on the play side of the blade, usually covering the majority of the surface with minimal gold or other colors.
