This pendant features a 14mm fiber optic glass round stone that is hand wrapped by talented Mexican artisans in wire made out of the metal alloy Alpaca. The pendant measures about 5/8 of an inch in diameter and comes hanging on an adjustable 16-18 inch silver plated snake chain with a lobster claw clasp. Please see the gallery pictures for a size comparison. The shades and depth of the colors may vary, and the sizing may vary slightly due to the availability of glass.
