Thai 925 Sterling Silver Blue Quartz Dangle Earrings Pierced

This is a very long pair of vintage 1970s-1980s Taxco, Mexican Sterling Silver dangle earrings with onyx cab tops and long moving feather dangles. Marked Mexico, 925 for sterling silver quality, with a T for Taxco and partly worn maker letter that looks like "L".  These hyphenated markings were government issued starting in the late 1970s. Marking is likely a worn R and attributed to Melesio Rodriguez who was the long time foreman for The Margot de Taxco/Margot Voorhies shop. If you look at the distinctive small 9 part flowers that are applied to the top you can easily recognize that these are Margot de Taxco earrings. There were only 2 other makers assigned with the 114 maker mark. One was "TC" and the other was "TV" one of which made floral and rose motif jewelr while the other only made stone inlay jewelry. These long shoulder duster earrings are originally from the Margot shot. The onyx cabochon stones are 13mm each, bezel set, well cut, well polished and showy. They have no cracks or damage and are still shiny from the original polishing of the stone. The sterling silver is very thick, strong and durable. Extremely well made as you would find with Margot jewelry. Weight is 22.4 grams. Condition is excellent. No dents or dings, tears or deep scratches to the sterling silver. Some light faint surface age wear only. Clean but not freshly polished out. They are extremely detailed and very, very well-made having deep obvious recesses in the feather/long leaf dangles, textured leaf end that look like cut off twigs, separately hand applied flowers and balls on the edges. This is a lovely beautiful pair of long, showy shoulder duster earrings for your vintage Mexican silver jewelry collection. See below for AI verification.
