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 liked the selection of gems, and price. I did not like your PayPal process. I already have a PP account and you want me to sign up for another.
