About Each Company


Clean Origin. Founded by Alexander Weindling, third-generation diamantaire and former global managing director for Georg Jensen; Ryan Bonifacino, former chief marketing officer and digital VP of Alex and Ani; and Terry Burman, who served as CEO for Signet Jewelers, Sterling Jewelers, and chairman Zale Corporation. This group of diamond and jewelry veterans know a thing or two about the industry and saw a new-age of diamonds in lab-grown. In fact, at Clean Origin, you won’t find any mined diamonds in any product. From the large center stones to the accent diamonds lining the band of a pave ring, each stone is 100% man-made. As a digitally native brand, products are priced extremely competitively due to lack of overhead found at other brick and mortar stores.

Diamond Foundry. Established in 2013, this San Francisco-based company was founded by a group of engineers on a mission to figure out how to create a lab-grown diamond. However, after figuring out the science behind man-made diamonds, it took them a while to dive into the design side of engagement rings. For a while, Diamond Foundry simply worked with partnering designers to distribute their stones. Today, their website allows you to ‘customize’ a ring with limited attributes and design options. And, although lab-grown diamonds usually cost anywhere from 20-40% less than mined diamonds, Diamond Foundry states that their diamonds cost just as much, if not more than their mined counterparts.
