I purchased a lot of black opal rough from lighting ridge this was in the mix, it’s approximately 14mm x 19mm

this is my first post I may have posted this in the wrong area or this is not what the forum is for so please be aware I will accept any suggestions and advice thank you

Hi Bill , I cut a lot of Australian opal and it could quite easily be from Lightning ridge or Coober pedy at the end of the day it doesn’t make any difference because they are all classified the same when it comes to value , If that is a finished stone I would say about £80. When it comes to opal this site is worth checking https://www.opalauctions.com/auctions/dark-opal-semi-black/ . Also if you use facebook there are a few groups for Australian opal .

Thank you very much for the info, I did join the group but I am having trouble trying to figure out how to post on their site.

Myself as well my Gemstones friend.
I’m new as well. The first one definitely appears to be Australian Opal with good play of color are more likely Etophian Welo Opal, that displays a ray of rainbow colors. Quite beautiful I think. Value would the Opalauctions.com that you where referred to is a great site for Opals.

Good happy looking at the gorgeous Opal world.
