14K HG Yellow Gold Green Jade (?) Ring ✨

We found this ring in a box of other items we purchased years ago, it was an unexpected bonus! It is stamped, but VERY faint. *Believe* we see 14KHG. If what we’re reading is correct, I believe that means it is heavy gold plated. We took it one step further and did an acid test. As expected, it shows 14k. See pic (test shown includes 10K/14K/18K.) Now, as for the “stone”… that’s not as easy. NO idea. It looks like it’s a jade color stone. Is it Jade? Plastic cabochon? Another type of green stone? We’ve never had anything like this, and the only thing we found that looks like this was a ring on eBay that sold - it was solid 14K with a “spotty” Jade stone. Ours is not solid 14k, and our stone is a solid color, and is smooth/lightweight. There you have it, that’s all the information we have. Please see all the photos and make your own determination as to age, origin, and materials. It’s a beautiful ring! Thanks very much.
