Beautiful vintage Mexican blue turquoise brooch. The silversmith has used a blue turquoise stone with black matrix and mounted it into a deep and tight smooth silver bezel. The artist wraps the setting with heavy twisted wire and finishes by attaching a safety locking pin/clasp on the back.

The brooch measures 1 1/8” by 1 1/2” across and weighs 14 grams. It’s stamped TS-79 - .925 - MEXICO - Double Stacked Trees by the silversmith. Mexico has a government registry to keep track of their silversmiths. Best I can tell is the “T” stands for Taxco, Mex, the “S” is either the initial of the silversmiths first or last name, and “79” stands for the 79th registered silversmith with same city and initial. I believe the Double Trees relates to a shop mark. $156.95
