For JC’s only,  Solid Dragon’s Eye = 41 stam gem.  JCs can use 3 of these and they are prismatic gems, meaning they match whatever color gem slot they are placed in, so they can be used to meet the socket bonus of the item.

Solid Majestic Zircon = 30 stam blue gem, epic quality.

Solid Sky Sapphire = 24 stam blue gem, rare quality.
