‘Rosie’ Rosarita Ring.

Rosarita on an embossed sterling silver band.

Rosarita is a unique by-product of the 1960's - '70's gold refining processes in Alaska.

The process created the slag by-product which is gold infused glass.

The base material is silica mixed with gold at high temperatures.

This stone is becoming scarcer over the past few years.
