Sterling silver Yooperlite ring, I just recieved these while in Tuscon Arizona for the Gem show. These rings are absolutely gorgeous. The silver smithing is world class, and the polish on the Yooperlite cabochon is the best I have ever seen.
This ring is shown under longwave 365nm uv light and white light.
You must have longwave 365nm light to see the fluorescence (glow).
