Some people want their cremated ashes blasted into the sky in a firework while others choose to be scattered at sea. Now there’s another option being offered by diamond-growing labs around the world, the majority of which are based in Switzerland.

People can choose to have their remains exposed to extreme heat and pressure to create a man-made memorial diamond. The stone can then be cut, polished, engraved and mounted, to be worn as a treasured jewel by a loved one.

Afraid of fumbling and misplacing that very large, very sparkly engagement rock? Why not just pierce it onto your ring finger? Dermal engagement piercing is the latest trend in matrimonial jewels sweeping social media and takes the concept of eternal love to a whole new—and more painful—level.

When cut and varnished, these “surgical souvenirs” make stunning adornments for necklaces, earrings and even cuff links.
