I was a little unsure how I would feel about these, but decided to take a chance. They are nice and light yet made with quality and strong hooks. Absolutely love them.
This sterling mounting is 3/4" at the widest part, slightly smaller than expected. The black obsidian stone is 1/2", also smaller than expected, but still lovely to wear. It is on a 17" silver necklace. It is a quality piece.
