This necklace is awesome. They don't come on the market often, and this one has been in my collection for a long time. First of all, it was made by a woman, Rose Haley Long, a Navajo. She has been using her stamp since 1973. According to Barton Wright's and Gregory Schaaf's books, this is a correct marking for the artist. Secondly, these are the best matched set of natural Cerrillos mine turquoise I have seen. The stones are greenish rather than bluish and have no matrix. Cerrillos is the oldest known mine of any kind in North America. Entirely hand made with a naja 3" tall by 2 1/2" with 6 dog tooth bezel set cabochons and 4 feathers . There are 12 squash blossoms with a feather and similarly set cabochons on a double row of hand made bench beads. Hook closure. 23" long. Weighs 7.6 ounces or 215 grams. Acid tests as sterling. This is rare. I took some of the photos without flash to highlight the luster and color of the stones.
