Architect Frank Gehry’s new jewelry collection for Tiffany & Co. launched recently with celebrity studded parties. There’s a surprising range of styles, six motifs and at least 120 pieces. Most are in silver, but various exotic woods, jade, quartz and of course gold are also featured. There’s a chunky bracelet made entirely of Cachalong opal, a porous stone similar to mother of pearl. I also noticed a ring in “black gold” which was new to me; the alloy can be made by several methods. The dominant motif in the collection seems to be the abstract fish which appears in a multitude of materials. The orchid earrings, however, are selling extremely well.
