Lorraine Schwartz dresses up the stars

Lorraine Schwartz, a New York diamond dealer/designer, knows how to give stars even more glitter, the USA Today reports.

For Sean Combs’s, a.k.a. P. Diddy, Moroccan birthday party in November, Combs wore Schwartz’s 20-carat canary-yellow diamond ring valued at $750,000, square diamond-stud earrings (11 cts. total, $250,000), and a 60-ct. yellow diamond bracelet ($700,000), the newspaper reports.

Schwartz wouldn’t tell the newspaper whether those sparklers were bought or loaned; saying she doesn’t like to name-drop, but Combs is a customer. ”With Puff, it’s always the best of the best,” she reportedly said.

Schwartz says her ”eye of protection” bracelet, retailing for about $6,000 and available at Neiman-Marcus Beverly Hills, is the hot item. (Matching necklace and earrings are available.) The bracelet is supermodel Naomi Campbell’s favorite Schwartz piece. Other celebs who wear it include Elizabeth Taylor, Barbra Streisand, Madonna, Angela Bassett, Britney Spears, and Elton John.

Schwartz’s next big thing for famous necks is a diamond locket due this spring, the newspaper reports. It will cost $4,000 to $8,000, depending on the style. Fred Leighton is among retailers who will carry it.

Schwartz serves lunch daily at her Fifth Avenue offices for her by-appointment-only clients.

Her jewels also have been seen on Nia Vardalos (My Big Fat Greek Wedding) at the recent Glamour Women of the Year Awards; on Courteney Cox Arquette and Lisa Kudrow for Monica’s (Arquette) wedding on Friends last May; and on Allison Janney (The West Wing) at the Emmys.
