This is a beautiful large stone ring made from silver and Picture Japser. Picture Jasper, also known as Landscape Jasper, is named for the "scenes" usually found on a stone. When I look into this one with a jewelers loupe, it appears to have a grouper fish on the surface. Funny! The stone is 3/4" long and 1/2" wide and is elegantly mounted on a very rare sterling silver adjustable band. It is currently set at a 6 1/2. It is a bountiful ring and will bring alot of attention! The inside is signed sterling with a makers mark of a C in a crown. Perfect!
