Vintage Heavy and Large Sterling Silver Turquoise Ring

Offering a large sterling silver ring featuring a large, teardrop-shaped light blue turquoise stone with natural white veining. The turquoise is saw-tooth bezel set with a rope border and 4 raindrops and 1 feather. This large size is designed to have a powerful presence on the hand. There is hand stamping on both sides of the shank, and the shank is 1/4" wide at the bottom. It is hallmarked in the center but I'm not able to ID the marker other than Navajo. The stone is 1-3/8" long with 1" at the widest part. Weighs 21.92 grams, size 11,5
