The review email came 2 days before I had actually gotten the ring. So, it had me a bit worried that someone else had picked it up. I sweat it out for a few days and it did come. The description, pictures and size were exactly what was show and what I had ordered. I am just hoping I have the right size and do not need to exchange it. Super handy that they include their own ring sizer with each purchase for that just incase I had also asked for discreet shipping, just incase he was to get the mail. And they made sure their logo was not on the label. My neighbor said a very well dressed, elderly man delivered it. Perfect! Thank you very much! Here's to hoping for 0 exchanges!
