SEMI-PRECIOUS GEMSTONES
Natural stones cut into various shapes and forms. Please note that all styles containing genuine gemstones have natural surfaces and therefore the stones vary from piece to piece. No two stones look the same, and this is to be considered a design feature to be emphasized and appreciated, and not a reason for claim.
