One of a kind and fun. Intended to fit with the concave stacking rings, but able to keep you busy when the need to fidget strikes. Black rhodium featuring a concave comfort band bead set with rose cut marcasite and a top "spinner" set with a big rose cut black spinel, and for a bit of color, the top is girdled with rose cut red garnets. Fits like a 7 and not sizable. Inquire for the same design in custom stone and finish.
