Mila Kunis featured motherhood ring is a limited edition that costs $4, 800. The proceeds are aimed at helping fund a maternity center in Zambia, near the Gemfields mine. Kunis said that the ring is very special to her as she and fiancé Kutcher just welcomed their daughter.

"Carrying a child and bringing new life into the world marks the start of an incredible journey," Kunis tells in a video. "Throughout history, every culture has its own way of recognizing this extraordinary event, often with a gift for mother or child. Precious green emeralds are traditionally symbols of motherhood, wisdom and long-lasting love. But they are also a symbol for hope in many cultures."

Mila Kunis motherhood ring profits will be donated to assist the new Gemfields Nkana Health Centre and help people around Gemfield mines survive and live a good life.
