Turquoise, Oxblood Coral and Black Jade stones have been hand cut and placed in this Mosaic Inlay Bracelet by Billy Jaramillo. His Sterling Silver Cuff is heavy and hand made plus the inside of the cuff has been hand stamped. The Sterling in this bracelet is 10 gauge. His work is phenomenal and he uses only top of the line stones in his jewelry. This cuff measures 1 1/4 inches wide and is a size 7 1/12. It is marked Hand Made, Billy Jaramillo and Sterling. The Stones used in this bracelet are Oxblood Coral, Black Jade and Burtis Blue Turquoise. The Burtis Blue Mine was formerly operated as the Florance Mine in Cripple Creek Colorado. Burtis Blue has a Mohs hardness of 7-8 which is a good high quality turquoise. The Black Stone is actually Black Jade rather than Jet or Onyx.
