With subscription-based businesses booming, you can now order pretty much anything in a convenient monthly box—including fashion jewelry. In 2012, Meaghan Rose WG06 aimed to revolutionize the jewelry-buying process with San Francisco-based startup Rocksbox, which rents, rather than sells, fashion-forward accessories to professional millennial women. For a flat monthly fee, members receive three stylist-selected items suited to their individual tastes, with an average retail cost of more than $200 per set. The Rocksbox collection contains 5,000-plus pieces from 30 independent designers, including Loren Hope, Kendra Scott, House of Harlow 1960, and Gorjana. With more than $10 million in funding and membership soaring, Rose hopes to expand to other categories, like clothing, and to countries outside the United States.
