The halo pendant - a center stone ringed by a frame of smaller accent stones - is a format with engagement ring heritage that translates well into fashion pendant territory when the center stone is color CZ rather than a diamond simulant. Rachel Zoe uses a green radiant-cut CZ at center with a white CZ halo in 14K gold over sterling silver, the color contrast between the green center and white surround amplifying the visual weight of both. 16-inch cable chain with lobster claw clasp and extender. The bezel setting on the center stone gives the piece a modern finish while the halo surround references classic fine jewelry construction - a productive combination that reads above its price point.
