The Enchant Scroll Band from Tiffany & Co.

This 128-year-old jewelry house is synonymous with cinematic Italian glamour, counting Sophia Loren and Gina Lollobrigida as longtime fans. Today, the brand is captivating a new generation of style icons with pieces like the snakelike Serpenti watch, set with brilliant-cut diamonds, and the sleek B.Zero1 collection, which just got a pavé-diamond makeover. 401 N.

Cartier’s history is flush with romantic diamonds, from Princess Grace’s engagement ring to the 69.42-carat “Taylor-Burton” rock that Richard gifted Liz with in 1969. The French house’s red box still makes hearts flutter—especially when it bears a diamond-encrusted Love collection bracelet, Trinity de Cartier collection ring, or Tank Anglaise watch. 370 N. Rodeo Dr., Beverly Hills, 310-275-4272

This family-operated brand may have small-town Italian roots, but it’s also hot in Hollywood (Sharon Stone and Brad Pitt have designed pieces for the house). In addition to customizable rings for weddings, anniversaries, and engagements, Damiani offers everyday diamonds like those in the new Damiani D.Icon Collection, which mixes ceramic, gold, and diamonds. 250 N. Rodeo Dr., Beverly Hills, 310-862-1320

Harry Winston
Harry Winston was nicknamed the “King of Diamonds,” and rightfully so—he owned the infamous Hope Diamond before donating it to the Smithsonian museum in 1958. His namesake house boasts rocks for all occasions, from the showstopping Ultimate Adornments by Harry Winston line, inspired by the brand’s copious archives, including the works of Ambaji V. Shindie, Winston’s chief jewelry designer between the years of 1962 and 2001. 310 N. Rodeo Dr., Beverly Hills, 310-271-8554

Tiffany & Co.
Legend has it that Tiffany & Co. invented the engagement ring in 1886, with an ingenious setting that made diamonds sparkle extra brightly. The house continues to churn out swoon-inducing bling, from its stackable diamond Celebration Rings—perfect for marking a special occasion—to its ultravibrant signature yellow-diamond collection. 210 N.
