Navajo Style Sterling Silver Turquoise Men's Ring Size 12 3/4

This large vintage sterling silver ring features a large oval turquoise stone of striking blue set in a strip bezel with a silver rope accent. The shank is adorned with stampwork on the sides. It measures about 1 5/8" in total length. On the underside of the ring it is etched with "BL". This may be a hallmark. The stone is a semi-domed cab which measures 30mm long by 13mm wide. It has a brown-black matrix and is polished to a smooth glossy finish.

As stated above, this ring is pre-owned and shows minor signs of wear. I performed both a "hot-needle" test and a "scratch" test on the stone. Turquoise is a semi-soft stone with a rank of 5 to 6 on the Mohs scale of hardness, often requiring stabilization (polymer or wax) for jewelry use. The ring is not stamped to indicate the purity of the metal, but I tested the metal with a GTE silver acid test. The results (red) indicate sterling silver. The metal is also not magnetic.
