Tiffany & Co. has brought even more sparkle to California.
The American jeweler has reimagined its boutique at South Coast Plaza in Costa Mesa, incorporating the elevated design aesthetic it introduced with the iconic Landmark in New York in 2023.
Tiffany has maintained a continuous presence at the mall for nearly four decades, opening a boutique of approximately 7,000 square feet in 1988, before expanding to a new location double the size of the original in late 2020. The West Coast flagship is now bigger and better than ever before.
Located on the main level of the Plaza, the new boutique covers more than 15,000 square feet. Tiffany once again tapped Peter Marino to spearhead the design. The legendary architect, who founded his eponymous New York-based firm in 1978, also worked with the house on the Landmark, the European flagship that opened in Milan in 2025, and the giant Tokyo boutique that opened last year.
The Tiffany pieces on show.
The store combines high jewelry, contemporary art, and Tiffany & Co.’s heritage with a touch of SoCal’s coastal cool. The beach may be the first thing that you’ll see, in fact, with digital screens showing classic California scenery by artist Oyoram. There is also a custom light installation by architect Hugh Dutton on the main floor that illuminates the house’s creations. On show are pieces from iconic collections, such as HardWear, Bird on a Rock, Knot, Sixteen Stone, T, and Lock.
In another homage to Cali, a series of objects from the Tiffany archives that have ties to the region will be on display. A piece of morganite from Mesa Grande, California, on loan from a private collection, will be showcased alongside archival designs featuring kunzite. That gemstone was discovered in San Diego County in 1902 and named after George Frederick Kunz, the chief gemologist at Tiffany at that time, who helped identify it.
The opening follows a period of substantial growth in Tiffany’s high jewelry business. LVMH, which acquired Tiffany in 2021, saw revenue increase 7 percent in the watches and jewelry category in the first quarter of 2026. Tiffany “achieved an excellent performance,” the comglomorate said in a statement, with HardWear in particular posting very strong growth.
