Moss Agate Size 9 Ring moss agate ring in size 9 with an oval stone set in a decorative openwork band. The design has a natural, understated look that works well for everyday wear or as a gift. Sold new without tags. * I am selling this ring from a family members collection. I believe it to be a moss agate based on the appearance. I don’t specialize in rocks and minerals so my determination may not be accurate.
