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

The site provided lots of detail, factual data, and good photos. I also like the availability of searching by price range as well as by the type of stone.

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
