This is a monumental Margot de Taxco design 5790 that is never seen. The sweep of the mermaids tail (or you envision it as feathers) is graceful and the repousse is stair stepped displaying great depth. Quality is shown with the heavy silver weighing 109 grams. The wearable length of the necklace is a comfy 17inches. Measurements of the drop are 3in. by 2.25 The earrings are 1.5in. long and 1in. wide with a weight of 20 grams. The earliest repousse was not backed with silver and this pair of earrings is made in this manner. They have a clip back which is original to the design. Margot could yield earrings that were large and comfortable by making them without the silver backing. This set has a superb presence. There are no flaws or damage, just LOOK AT THAT NECKLACE!
