Marvin Slim Statement Sugilite, Lapis and Turquoise Open RingGorgeous ring by Native American Silversmith Marvin Slim. Silver setting with very large sandy crystal on one end of the band, turquoise and lapis lazuli inlayed on alternate end. Stones meet but the band remains open, unclosed. While a stunning large statement piece, the stones rest between your fingers and do not carry the same weight as a ring of the same size with a center stone. Size 6
