Vintage Arte Orfebre Peru Sterling Incan Ring || 5

Women's size 5 sterling silver ring made by famous artist Arte Orfebre in Peru. I literally dug this ring up in my backyard when I was in 3rd grade in 1978 and have hung onto it all these years. I am just finding out about the artist and he is quite an artist/jeweler. Ring hallmarked 925 and the artist's last name (see photos) It is mid-century, made in Peru!! I have not cleaned up this ring, will leave it to the buyer. Thanks and please let me know if you have any questions!!
