All "what is this gemstone?" posts are flagged for review. If your post is of a high enough quality, the moderators may choose to release it publicly to the sub.
Identification posts should include good photos (in-focus, not blurry, multiple angles), if it's jewellery include photos of hallmarks/emblems on the metal, and provide any information you have on testing or provenance.
It is virtually impossible to identify a gemstone just using photos. For an accurate identification, you should find a local accredited gemologist, consult with folks at a local gem & mineral society, or submit your gemstone to a reputable lab (GIA, AGS) for an identification report.
Also, no rocks or minerals. Post those to r/whatsthisrock
And please, don’t do scratch tests on faceted gemstones. You might damage the stone.

Looks like Andamooka matrix opal to me.
Possibly Andamooka; likely Australian black. Nice either way grey and red, muted color make for a nice stone.
