Kooh-I-Noor mirror

The Kooh-I-Noor mirror designed by Piero Lissoni is characterised by raw, irregular shapes that seem to be carved out of rock. 
The mirror is made from a single block of pure transparent glass with faceted, bevelled edges. 
This multitude of facets magnifies the material by giving the glass its brilliance. 

Its shape is reminiscent of the world's largest diamond, the Koh-i Nor or Kuh-e Nûr or Koh-i-Noor (Persian: کوه نور, mountain of light), a 105.602 carat diamond currently mounted on one of the British Royal Family's crowns, displayed with the British Crown Jewels at the Tower of London.
