The work of Los Castillo and most certainly design number 615 was a Margot van Voorheis design while married to Antonio Castillo. The necklace is thick and 1.25in. tall. This design also came in a smaller width but this example is the biggest one. The completely hand carved links with the bead work make this a time consuming endeavor. I like it best turned inward and the wearable being 16in. If worn outward like the last photo it has a wearable length of 17.25 inches. No damage or repairs and well kept. It boasts a natural patina with a weight of 100 grams. One of my favorite designs, just LOOK AT THAT NECKLACE!
