Peter Schmid of Atelier Zobel designs rings for men that really rock, like this platinum and sterling ring set with an oval phantom quartz cut by Tom Munsteiner. The rock crystal quartz is prized for the cube-shaped second crystal trapped inside, and then sculpted by Munsteiner with incisions at the base. Platinum bezel, oxidized sterling ring. 1-1/8" w across the finger x 1" x 1/2" h.
