Coral Cabochon

My educated guess is this is Apple coral with some type of silver stabilizer. I’ve never seen anything quite like it and that’s why I purchased it at the gem show in Quartzite Arizona many years ago. It majors 53 mm long and what approximately 4 mm thick. It’s a very very cool stone. I lightened up the very last picture so you could see it’s definitely coral. It’s not quite as bright as that in person but it’s not as dark as the first picture either. If you want I guess I could take a video. Just ask.
