New York jeweler Mish debuts his stunning new Florida flagship.

For three decades, New York jeweler Mish Tworkowski has been known as much for the exquisite baubles he designs as for the decorated-to-the-nines spaces in which they are displayed. An inveterate decor buff, he and his partner, the architect Joseph Singer, have presented Mish jewelry in spaces ranging from an Upper East Side carriage house to a storefront on SoHo’s Bond Street, complete with a lacquered purple door, rock-crystal-and-tiger’s-eye doorknobs, and antique furniture.

So when Tworkowski announced last year that he was relocating his flagship to Palm Beach, devotees of his designs waited with anticipation for the unveiling of his latest showcase. On Monday, he officially opens for business (by appointment) in a space he designed with Singer and interior designer Katie Ridder in the heart of Palm Beach’s shopping district.

“The light and bright colors in Palm Beach make my heart sing,” Tworkowski explains of the move to Florida. “Plus, I think change keeps you young. We had a house down here and love the lifestyle, and I’m a huge gardener. So it made sense.”

It took three years to find the perfect space. He found it in a charming 1924 pink stucco building (formerly a Bonwit Teller department store) designed by Addison Mizner, the society architect who popularized the local Mediterranean Revival style. Singer renovated the 2,000-square-foot ground-level store space, relocating the entrance to the loggia overlooking Palm Beach’s historic Phipps Plaza. Meanwhile, Ridder brought her color prowess to the decor—from the gold and blue patterned Brunschwig & Fils Byzantine Swirl wallpaper in the reception gallery, where a vintage desk is topped with baby blue leather, to the Trellis room, where the lavender walls are clad in lattice work. “The interiors reflect Mish,” Ridder says. “Brilliant creativity and mirthful imagination.”

Framed showcases throughout display Mish’s spectacular collectible jewelry. For the opening, Tworkowski is unveiling his new Cabana bracelet, which features 15 turquoise charms shaped like shells and sea creatures (a percentage of sales is being donated to the Preservation Foundation of Palm Beach). He is also debuting a new collection, Why Knot?, with ropelike knotted chains in 18-karat gold, paired with gemstones and pearls.

In transforming the space, which at one point after Bonwit’s closed was a bank, Tworkowski and Singer uncovered an old vault under the drywall. “We didn’t want to have to break into the safe,” Tworkowski says. They brought in a vault specialist who realized it was set to a universal code used for decommissioned safes. Now reset, with its stainless steel door polished to perfection, it’s the perfect amenity for a jeweler.
