ODONTOLITE Turquoise Fossil Sterling Silver Navajo Ring Vintage Size 10.5
Very unique ring, unsigned, likely Navajo or Native American made. Beautiful craftsmanship with hand filed applique leaves, twisted wire and a straight bezel. Nice split shank fits a size 10.5
I was told by an expert that the stone is not turquoise but odontolite, which is fossil that has acquired its turquoise color through a similar process as turquoise. Yet another expert said that it is dyed ocean pediment. Another suggested it could be mollusk fossilized turquoise, which is common in Nevada near Battle Mountain. I have never seen anything like it and it is beyond the breadth of my scientific knowledge as far as geology goes. So it could be turquoise or odontolite, or some other ancient marine stone, but that does not take away from its masterful beauty.
