I love the quality, presentation and the price of the stones. I love the identification card - report they send with each stone.

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.

I did not realize these stones were of jewelry quality. They are really beautiful, just not what I was expecting which was more of a natural stone.

Appreciated the selection. Jadeite is hard to find under $100. Website has alot of variety.

I visited several online loose stone shops trying to find rare stones. I finally found one that I've been looking for here, and very satisfied. Looking forward to receive the item in 3 weeks.
