Smokey topaz sterling vintage ring

Purchased in Mexico 925 stamped sterling silver just over 6 grams in weight. About a size 7, on my middle finger but don’t know a buyers finger measurements so place the ring beside a Canadian nickel, dime and quarter to get an idea. unique design on side of bands. The ring is a nice statement piece to have and stands out with any outfit. Doesn’t come in the plastic case but will ship in a small box.
