Hi I hope this is OK to post here as I have seen others asking about other fossils which aren’t exactly in their original form... I picked this ring up at a thrift store because the color just screamed coral to me... I thought it may have just been a costume piece but apparently it is most likely an antique. I polished it up and I am now fairly certain it could be red coral. It is hard for me to get a really good close up pic since I only have an iPad but if anyone has any tips on IDing coral that doesn’t involve sticking any acid on it since it is possibly a valuable antique. I have a little 15x lens and up close the “banding” actually looks more like finger prints or light layers..which is what the other photos of coral cabocons seem to have. I posted it in an antique jewelry group but no one was knowledgeable about coral...the best guesses they has was agate or glass (defiantly NOT glass)..so I thought I would ask the best fossil identifiers in the world.. thanks you!
I will post the original and polished photos.
