I was looking for high-quality amethyst on this site, and I was able to compare size, color, and weight in detail before making a purchase.

Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.

All items were delivered on time with all items meeting or exceeding my expectations. Cut, clarity and color were very close to the photos and description.
