Hello, we’re Lightbox.

ALWAYS 800 USD A CARAT

Most lab-grown diamonds are priced just like natural diamonds, so size + quality = rare & expensive. At Lightbox, high quality comes as standard. The price just reflects the size. 

Our leading technology also means we can create lab-grown diamonds in colors that are extremely rare in nature, like blush pink and soft blue. And the price? No difference. Always 800 USD a carat.
