Rosarita (Gold Infused Glass) Sterling Gemstone Ring

This item is adjustable to fit most all fingers. It is adjustable at the base of the ring, so there will be no snagging, or pinching. What is Rosarita??? See below-
Rosarita is a unique material, which derives its exceptionally rich, red color from the process of gold refining. It is a unique by-product of the 1960s and 1970s gold refining processes. Alaskan beach sand was smelted for its gold content and the slag by-product was Rosarita, which is essentially a gold-infused glass.
