If you've finally scored one of 's perpetually sold-out Rivière necklaces, then you'll want to get ahead of the pack and pounce on the LA-based line's first-ever , debuting today! Inspired by founder Meg Strachan's grandmother's wedding ring, it's made of 14k-gold and studded with Dorsey's signature sparkling lab-grown diamonds. It looks like a million bucks, particularly when styled with the other pieces, above, and I love that it's both a cocktail party conversation starter and everyday-cool. Be sure to check out the new gorgeous white sapphire and bracelets, too, all ...for now.
