Vintage Sterling Silver Sleeping Beauty Turquoise Butterfly Brooch Yazzie Family. The top part of the wings horizontally measure 1 7/8 in width. The turquoise is real. The Yazzie family signed L Y. Weighs 8.68 grams. I can dip this in sterling cleaner at no charge. I do not dip the sterling jewelry before I sell it unless asked because many people prefer it naturally tarnished. It takes a while to get it to look this way. Jewelry shelf A drawer 3 040925 ESS 060925.
