Shiffon Co. on Glamour: 38 Genuinely Great Gift Ideas That Give Back to Incredible Causes

Half of the proceeds from Shiffon's Duet Pinky Ring help fund seed grants for female entrepreneurs and start-ups that support women. It's the brainchild of a collective of female entrepreneurs and is a favorite of feminist celebrities—when Emma Watson lost a meaningful ring that was given to her by her mother, she replaced it with the Duet, and Nicole Kidman and Shailene Woodley both wore the ring to the Emmys in the name of women's empowerment. A silver version is also available for $90.
