Our mission is to make the sparkle of a diamond available for more people, more often. We’re constantly innovating our world-leading technology—to make bigger, better, and more accessibly priced lab grown diamond stones. Lightbox Jewelry launched in 2018, and was backed by a $100m investment from De Beers Technologies to bring its patented diamond synthesis technology to consumers – offering them laboratory grown diamonds of an exceptional quality and at an accessible price. Lightbox now operates as an independently managed subsidiary of the De Beers Group.
