This cabochon came from an estate purchase. It looks brand new but it must be from the 1980's or before. It measures 1 9/16x 1 3/16. The second photo is of the back. The back is flat the front has a slight curve to the face. It is super smooth and shiny. The colors range from pale tan to a very vibrant orange and almost a clear sheer swirl to the bottom of the stone. Truly an amazing piece.
