Vintage Turquoise Native American Sterling Silver Statement Pendant Necklace ETC9842

This is a vintage Native American sterling silver turquoise pendant necklace. The pendant measures 2 1/8" long x 1 3/8" wide. The back is signed by an engraving tool. I cannot make it out for certain. Maybe Kayper? The turquoise nugget measures 25mm x 14mm. The chain measures 24" long and has a hook closure. Total weight of the necklace is 31.5 grams. There is no visible damage. Light vintage wear can be expected.
