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

I really liked the email, and the link that help return me to the site. I didnt have access to my card info while checking out and I had to put my phone away so I lost the tab. Fortunately, since I did give an email- they sent me a link that brought me back to where I was. Greatly appreciated
