I am totally impressed with the super nice & pretty job by this artist. I am not familiar with the artist. It is signed T. Crespin on the back side that appears to be a base of black stone or onyx for the inlay to set on. The inlay is of turquoise, picture jasper, tiger eye, large heshi brown shell & again of black stone or onyx. Sterling Silver running throughout the inlay. The clasp is also sterling that is ajustable by 2" so this can be 18 or 20" long. The widest link of inlay is 3/4" wide.
Just beautiful! Can't go wrong with this piece!
