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

All items were delivered on time with all items meeting or exceeding my expectations. Cut, clarity and color were very close to the photos and description.
