This is an awesome, large hand made ring. It features a terrific large oval turquoise stone. It has a great sky blue color with a touch of white which gives it an unusual depth at different angles. This turquoise stone is the seafoam or spider web type. We do not specialize in turquoise but think those terms do apply to this type of stone. We think this ring is Native American Indian Navajo made, but we do not know any history on this ring. There is a rope style detail around the stone along with a scallop pattern and a feather design in the silver setting. This ring is not marked but is guaranteed to be silver. It is in excellent condition. It is a size 8 1/2. The setting measures 1 1/2 inches x 1 3/8 inches. This is a fabulous ring that is a must have piece to add to any indian jewelry collection!
