sought-after ! Vintage 10k Gemstone Ring (Samuel Aaron)

This is an absolutely exquisite vintage solid 10K gold ring with gemstones by Samuel Aaron. The Jeweler that tested the ring for me the clear stones are amethyst (which I always thought are purple), but he also mentioned that the center stone is called Prasiolite. It's natural Prasiolite (light green) & it is more valuable than purple prasiolite. It's interesting but like a foreign language to me. I really dont know much about gemstones at all. It kinda reminds me of aquamarine but more green in hue. The ring is in incredibly good condition. it's been in my storage facility since I received it from a late relative 25+ years ago. The ring is a size 8, and it's marked 10K with the letters THL (Samuel Aaron jewelry) & a copyright circle. Feel free to ask any questions. Thanks
