Probably one of the last items purchased at the Tucson Gem Show which would date them around early 90's. Minty condition - carefully stored old stock. Crescent shaped moon with a small oval turquoise cab channel set into the middle. Nice southwest motif. Not stamped but tested for sterling and I do know where I got them. They measure just over 3/4 of an inch long - nice size. The sterling silver fish hooks are stamped 92.5.
