Whether you aced astronomy, or just think space is the coolest, these colorful pendants add a touch of galactic fantastic to your look. Cameron and Rebecca Stern arrange a "specimen" of stardust (pigmented paint, glitter, gold leaf) underneath plant-based resin, framing it in a sterling silver hexagon. It's a nod, they say, "to past explorations and excitement as to what is yet to be discovered." Kind of like the contents of your jewelry box. Handmade in New York.
