Swarovski unveils lab-grown coloured diamonds

The 16 stones have names referring to their colours, like Gothic Cognac (a deep orange), Cubist Sky (sky blue), Androgyny Flamingo, (vibrant pink), and Heavy Metal Cherry (a deep red). Swarovski isn't the only big name tapping into man-made jewels, the De Beers Group unveiled its laboratory grown gemstone collection in 2018.
