Wow!! This is a killer bracelet. Stunning inlay of turquoise, onyx, spiny oyster & an dark opal diamond shape center. A super nice job of some channel & cobblestone style inlay. The back sides & the inside all stamped out in great design. The artist halmark is KC & marked Sterling. It weighs 73 grams!!! I am sorry to say the person I purchased from had no information on this artist. If anyone out there does I would love to hear from you. I really don't have a definate idea of it's worth. I know simular ones go for around the 15 hundred mark...I am selling for less not knowing for sure. If I find out more on it, it will most likely be marked up rather than down so get it before I figure it out! LOL The back opening is 1 1/4" & inside cuff measures 5 1/2". This will fit a 7" wrist. Mine is 6 1/2 & it i just a little big. Please note this can't be adjusted at all for fear of popping out the inlay.
