Sterling Silver Handmade Custom Vintage Ring

This is a beautiful vintage handmade, custom Sterling silver ring. I inherited the ring from a grand parent in 2001. It originally belonged to my late uncle whom I never actually met. He passed when I was a child. My grandmother told me he had the ring custom made by a jewelry artist around late 69-70. he passed in 75 and that's when my grandmother inherited the ring. I honestly don't think the ring has ever been cleaned or polished since it was first made, so any dirt or tarnish on the ring is original from when it was worn in the early '70s. He also has the same artist design a similar bangle that unfortunately ended up with another relative & I never had a chance to see it. It's approx sz 8 ½ with an open ended design so I'm sure it can be adjusted, but I've kept it exactly how I received it. I've never actually worn it & have had it packed in my storage facility all these years. Thanks
