Boulder Opal Silver Ring
This ring features a natural, untreated piece of Boulder opal from Australia. This was one of my finds from Tucson. I picked this piece up as well as some others from a dealer directly from Australia. Its opalescence carries colors of purple, blue, yellow, orange and brown. This precious stone measures 18mm x 25mm and sits in a sterling silver, prong setting. This ring is a size 7. Rings can not be resized.
