Swarovski Elements has asked 15 celebs and designers to re-create limited-edition Gaia+Gino vases using Swarovski crystals, with all the results being auctioned off online to benefit Housing Works. The one-of-a-kind looks are all pretty incredible, though our favorite has got to be the design from Mary-Kate and Ashley Olsen, who donated their vase—dressed in a beaded collar jacket and tulle skirt—under their Elizabeth and James label. Other celebs designing for the cause include Bethenny Frankel, Tinsley Mortimer, and Carson Kressley (who, to be fair has some real design chops). Click through a gallery to see which vase you’d bid on!

Vases are available at through December, 20th.
