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.

Absolutely love the website, selection and products. Can you guys add a gemstones with inclusions tab. I like those it'd be nice to have them all in one place but i do understand it would be alot of work to go through and categorize them. Thank you anyways

I like the site, it's easy to navigate. There are sometimes items I'm looking for that aren't there, but mostly I can find what I need.

Wonderful experience so far. I rarely order from vendors online but Ia'm hoping the gem I ordered is of good quality and not a fake.
