There is something calming, elegant and tactile about rock crystal. Elsa Peretti has used it in many designs in fairly innovative ways. This Sphere necklace takes circular rock crystal beads, threaded with thick black silk knots. The fat knots remind of the intricate work found in passementerie tassels.
It’s available exclusively from Tiffany and sells for USD$4,500.

Obscene price which is de rigeur at Tiff’s. Luxury should not be obscene, and the rich do understand value.
