This Saturday marks Mandela Day, which celebrates international freedom fighter Nelson Mandela's 91st birthday and includes a star-studded event at Radio City Music Hall in New York City.

Mandela, the former head of the African National Congress, spent 27 years in a South African prison for his work against apartheid. South Africa now faces a devastating HIV and AIDS rate just as destructive as the racial subjugation it once contended with.

Mandela's Robben Island prison number, 46664 -- the same name as his nonprofit -- now manufactures precious jewelry with the number etched into it. Sixty percent of the proceeds go directly to combating HIV and AIDS. Celeb supporters of the 46664 bangle program include Angela Bassett, Alfre Woodard, Laurence Fishburne and Clint and Dina Eastwood, among others.

Not only does the 46664 bangle initiative fight HIV and AIDS through social and medical programs, but it actually creates jobs. By hiring local South African men and women, many of whom are living with HIV/AIDS, hundreds of families are earning an income from the manufacturing, packaging and distribution of the hand-crafted bangles. New bangle owners can go online and track how their purchase money is impacting the fight against AIDS.

The 46664 bangles range in price from the all-new $19 copper bangle, $199 for the silver bangle, $5,900 for the 18-karat gold bangle, $6,400 for the 24-karat gold bangle and $12,900 for the platinum bangle.

If you happen to be in New York this weekend, you can also support 46664 by attending the Mandela Day Concert celebration at Radio City Music Hall, held Saturday, July 18, at 8 p.m.

Stevie Wonder, Aretha Franklin, Josh Groban, Alicia Keys, Will.i.am, Queen Latifah, Wyclef Jean, Dave Stewart, Lil' Kim, Carla Bruni-Sarkozy, Jesse McCartney, Cyndi Lauper, Gloria Gaynor, Zucchero and African artists such as the Soweto Gospel Choir, Angelique Kidjo, Baaba Maal, Freshlyground, Emmanuel Jal, Loyiso, Sipho Mabuse, Vusi Mahlasela, Thandiswa Mazwai and Suzanna Owiyo will be among the lineup of artists performing.
