Morlock Posted October 21, 2021 Share Posted October 21, 2021 It could be fluorite depending on exactly what type of light was used on it. Quote Link to comment Share on other sites More sharing options...
clay Posted October 21, 2021 Share Posted October 21, 2021 It's clearly glass. "Gemstones" don't have air bubbles. 1 Quote Link to comment Share on other sites More sharing options...
obieblue Posted October 21, 2021 Author Share Posted October 21, 2021 Thank you I've been told before it was glass it's just weird it will change colors like that under different light , but it's purple all the time only under a yellowish light bulb does it turn light green Quote Link to comment Share on other sites More sharing options...
Bedrock Bob Posted October 21, 2021 Share Posted October 21, 2021 If you add yellow to purple you get green. It's a wavelength thing. Quote Link to comment Share on other sites More sharing options...
