Navajo Style Sterling Silver Ring Turquoise Pyrite Size 9

This large vintage sterling silver and turquoise ring boasts a large teardrop stone set in a strip bezel with a silver rope accent. It measures about 1" in total length. On the underside of the ring it is etched with "BL". This may be a hallmark. The stone is a domed cab which measures 22mm long by 16mm wide. It has a black matrix with pyrite inclusions and is polished to a smooth matte 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.
