All CS2 Classic Knife Case Hardened Blue Gem Patterns: 403 and Tiers Explained

The CS2 Classic Knife Case Hardened is one of the most sought-after knives in CS2. While the Case Hardened is a very rare knife skin by itself, the Blue Gem patterns are considered to be the best of all. A Blue Gem is a rare pattern found on all Case Hardened knives, that have more blue on the exterior than usual. This can impact the price and appearance massively – Blue Gems cost a lot more than normal knives.

All Classic Knife Case Hardened knives are randomly assigned one of 1,000 seed patterns when they are dropped from a case. Yet, only some of those are considered Blue Gems, which is what makes them so rare. These patterns have been separated into different tiers by the Counter-Strike community, based on the amount of blue found on each.
