Rad Rings

How cool are these rings? The one on the left leaves an indent on your finger after wearing it for so long. Kind of like the opposite of that funny callouss you get from writing all the time? That way, if you ever take it off, there is a small heart indentation! So sweet.
The other ring on the is the groom's ring, but I think it could be for both (both these rings are very sleek & unisex. Kind of unconventional & modern.) because of the design. The ring has the finger print of your spouse engraved on it. Precious!
