A new mysterious type of gem has been datamined on the Patch 10.0.7 PTR–Primordial Stone Gems! While absent from the patch notes, we’ve datamined a number of interesting effects these gems provide.
Based on the Global Strings, these gems will only fit into Primordial Sockets found on specific pieces of gear. One of the new items datamined in today’s Patch 10.0.7 build is Onyx Annulet, which comes with three new sockets.
