From a Casas Adobes neighborhood estate in Tucson is this I believe 1960's or perhaps earlier 1970's Navajo turquoise and silver pendant pin. Seven (7) attractive blue turquoise sets and a pair of wing like repousse leaves - the artistic vision here is deceptively simple. Crafting it, however, took more skill than you might realize in those days before power tools came to dominate the craft. The deep blue stones show a distinctive reddish brown and black matrix.
They really remind me of Bisbee material I've seen, though pinning localities is not my forte - have a look to judge for yourself. A pendant loop and a pin and locking clasp provide appropriate nods to versatility. The overall look here has a kinship with mid century "modern" studio work, and you absolutely know it has nothing to do with anything recent. Put another way, it has "the look" you require. There are no marks, which of course is absolutely normal for the time of making.
Weight is good for the form at about 7.6 grams on my portable digital scale. Condition is quite fine with an untouched aura of time to the silver surfaces as seen in the pics. Be aware I've avoided every urge to refresh away or "improve" upon any natural toning - you want that done you do it.
The local lapidary turquoise looks great, all stones being original to this ornament. Both suspension loop and the pin / clasp work exactly as they should.A look at the pics should give a good idea of appearance and condition. Size is about 1 15/32 in. Vertical including the loop and 1 in. I don't know what else to say, so there you are. If you prefer vintage over things more recently made and are partial to blue, or simply wish a single immediate improvement to the ambiance of each day, this will have great meaning for you.
