Each of the 9 stones measure 1"1/8 x 1/4" and set in a channel created with 2 pieces of triangle wire that have been notched with detailed saw cuts. The inside of the bracelet has a patten stamped down the center giving this bracelet an extra element of style. Onyx is a chalcedony quartz that is mined in Brazil, India, California, and Uruguay.
