I pulled this from a case a few weeks ago
Pattern 432
The non-playing side has a significant amount of blue, but I'm not seeing this pattern listed anywhere on the blue gem guides for the Kukri Knife (for example > Steam Community :: Guide :: Kukri Case Hardened: Blue Gem Patterns)
Is this a blue gem? or is there something knocking it down from even Tier 4 on the linked list above?
