Samuel Aaron Vintage Ring Solid 10k & Gemstones

This is an absolutely beautiful vintage solid 10K gold ring with gemstones by Samuel Aaron. The Jeweler that tested the ring told me that the clear stones are amethyst & the center stone is called Prasiolite. It's natural Prasiolite (light green). 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 gemstone but slightly more light greenish. The ring is in very 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 & a copyright circle (Samuel Aaron jewelry) . Feel free to ask any questions. Thanks
