Sophie Ratner founded her eponymous jewelry line in 2016 on one strongly held belief: that diamonds should be enjoyed daily, not just on special occasions. Her designs—dainty earrings, light-catching pendants, and dynamic rings—go everywhere you do, from morning matcha runs to nights out with friends. Bonus points for sustainability: Everything is handmade to order in New York City from lab-grown diamonds and ethically sourced fourteen-karat gold.
