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.

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
