Rebecca Collins blue chalcedony clip earrings sterling Dallas Texas signature

Rebecca Collins' jewelry is ultimate rich-girl chic, all of them subtle statement and unmistakable pieces. This pair of clip-on earrings is, as I recall, blue chalcedony, that wonderful cloudy blue stone that even the uber-stylish Duchess of Windsor chose for some of her spectacular jewels. A marquise shape mounted above an oval, each measures a bit more than one inch high. See photos for precise measurements. mounted on sterling silver signed with Collins' signature and "Dallas, Texas." I bought all of my Collins pieces at Neiman-Marcus before 2009, when she stopped selling her line. Original price about $500. Your questions welcomed.
