Eva Longoria, Beyonce and Pals Do for ‘Diamonds’

Want a piece of Eva Longoria Parker? Get in line, and bring your checkbook.

The teeny Desperate Housewives beauty is giving up one of her favorite cocktail dresses for the Diamond Empowerment Fund, Russell Simmons’ charity to help educate regions where diamonds are a natural resource.

Reps for baller Tony Parker’s wife tell Celebuzz she is parting with a winter-white strapless mini dress by prominent Latin American designer Gustavo Arango.

“It is a personal favorite of Eva’s that she wore to a cocktail party,” reps tell Celebuzz.

Also up for grabs is a VIP package courtesy of Beyonce Knowles. Sasha Fierce is donating two tickets to the New York City premiere of her turn as Etta James in Cadillac Records. The premiere will feature cast members Adrien Brody, Cedric the Entertainer and Mos Def.

Festivities for the month-long auction kicked off last Friday in Dallas, TX, where former cowboy Emmitt Smith cruised to a fundraising gala in the Grey Goose Rolls Royce.

Kim Kardashian, Erykah Badu, Kimora Lee Simmons and the boys of Good Charlotte will also pitch in with garment and jewels, all up for silent and live auction at CharityBuzz.
