Vintage Native American Turquoise & Silver Ring One-of-a-Kind 16 grams

Vintage Native American Turquoise & Silver Ring - One-of-a-Kind - 16 grams. No stamps or hallmarks, appears to be of Native American descent but unsure of which Tribe. This ring was my grandmothers and passed down through our family. According to research of other similar listings and jewelers online, this ring appears to be from the early 1900s and is either made from Silver or Sterling Silver. I weighed the ring using a kitchen scale and it shows 16 grams total weight.
