Vintage Gold Ring With Large Prasiolite "Green Amethyst" Gemstone Ring In A Raised Setting

**UPDATE: After I filmed the video I found two tiny marks. It is inscribed MK and K14. I think it is prasiolite or what they incorrectly call, green amethyst. If anyone knows what kind of cut it is or if the stone is or is not prasiolite, please let me know in the comments below. Thanks : )
