LORENZ’S FORAY INTO FINE: Designer Dana Lorenz of collections Fenton and Fallon will unveil her first fine jewelry line today, a capsule collection created for Plukka.com. Staying true to her aesthetic, the five-piece Dana Lorenz for Plukka offering welds the punk and classic elements (like spikes and pearls) that Lorenz’s contemporary lines have become known for. Fashioned from 18-karat yellow gold, sterling silver, labradorite, lapis lazuli and diamonds, the two bracelets, necklace, earrings and ring will range in price from $1,200 to $7,500. The Web site, which launched over one year ago, will price the pieces in line with the “made-to-order” category of its unique retail model (which also includes fixed-rate items and its patented reverse auction Plukka Value Proposition). The collection will be available at Plukka.com through the end of August.
