I signed up myself about a month ago after complimenting several of my friend's pieces of jewelry and discovering they were all from Rocksbox. So far, I've received three boxes and scored a great Gorjana necklace and am debating the necklace featured above. It's great because I get to try the necklace with a variety of looks to see if I want to keep it. Spoiler alert - I'm sold!
Rocksbox is a great service and I highly recommend it both for yourself and for others on your wish list. Happy holidays!
