Jewelry designer Monique Péan’s newest collection was inspired by a simple concept: clean water. Now a charity collaboration based on the collection will send drinking water to those in need.

Ms. Péan teamed up with Charity: Water, a nonprofit group that operates in developing countries without access to proper sanitation methods. She says every piece in the collection is made with reclaimed gold and conflict-free diamonds, and proceeds from the jewelry’s sales will provide clean drinking water through the charity for as long as 20 years.

Prices range from $1,000 to $40,000 for a custom-designed statement piece and will be available in February at retailers Kirna Zabête in New York, Roseark in Los Angeles, Lane Crawford in Hong Kong, and Ikram in Chicago.
