White diamonds and black diamonds are the star features in a Valentine's Day collection of diamond necklaces designed by Demi Moore and Ashton Kutcher in collaboration with jeweler Jack Vartanian.



Moore and Kutcher have designed the diamond necklaces to raise money for their charity, the DNA Foundation, which battles child slavery.



To drive the point home, the diamond necklaces – available in white, yellow, or rose gold – are set in the shape of handcuffs. The pieces will be priced from $710 to $2,140, and 50% of every diamond necklace sale will go to the DNA Foundation.



The necklaces will be available until Valentine's Day, February 14.
