I’m looking to purchase this Opal as my first one! I have only what the seller has told me about it to go off of. I don’t know how to spot fakes, so I have no frame of reference for how authentic this is. Here’s what they claim it is:

Solid
Natural Ethiopian
Untreated
Set in 925 sterling silver
22mm Length x 13mm Width x 8mm Depth
8.7 Carat

They are based out of Jaipur india.

Any insights would be appreciated
