Within Counter-Strike 2, blue gem patterns on Case Hardened weapons are among the most sought-after skins. The term “blue gem” describes a top-tier Case Hardened item where the random pattern index produces a blade or body that is predominantly blue rather than the usual mix of gold, silver, and purple. The community tracks these patterns meticulously, assigning tiers based on the amount and placement of blue, with Tier 1 being the absolute elite.
The pattern index is a number between 0 and 999 that determines the exact finish on any Case Hardened skin. As of the CS2 2024 update, you can now read this index directly in Steam's inspect window, making instant pattern verification possible without external tools.
