Yoox.com is now my favorite jewelry stop. The online retailer launched Past & Present, a new area dedicated to contemporary and vintage jewels. In contemporary, you'll find modern pieces like skull earrings and chain-link rings. In vintage, there are one-of-a-kind necklaces, art deco earrings, and sparkly pieces, like these Unsigned Crystal Earrings ($85). Hurry, they're selling out quickly.
