Rare Vintage Navajo Sterling Silver and Red Coral Concho Link Necklace

VERY GOOD CONDITION WITHOUT BOX AND PAPERS. Vintage Navajo Sterling Silver Mediterranean Red Coral Concho Link Necklace 29.93gr Up for sale is a rare, authentic Native American handmade necklace. It features 8 flower-shaped concho links with traditional hand-stamped details and genuine red coral stones. Based on the exact information you provided—specifically that all 8 coral stones are perfectly calibrated and identical in size down to the millimeter (8.80mm x 4.60mm x 3.66mm)—this necklace was made around 1970 to 1975. Before 1970, Native American jewelers cut stones entirely by eye, making every stone slightly different in size. The perfect uniform calibration of your stones proves the jeweler used the specialized mechanical cutting gauges that became widely available in southwestern trading posts during the early 1970s jewelry boom.
