A diamond is a rare and precious find which has been treasured by humans for thousands of years. It’s the gift of love; a luxury product; an iconic badge of the glamourous. Or is it more important than that? Researchers at the University of Warwick, and collaborating universities across the UK, are proving that a diamond is much more than just a sparkly bauble. Scientists can grow synthetic diamond in the lab with the vision of using it in a huge range of innovative applications.
