If you want the rarest and most ethical diamond in the world, look no further than the Whistler Diamond.
Process starts with old growth yellow cedar burl charcoal. The activated charcoal then steeps in an old growth forest root system or canopy. This finely essenced charcoal is sent to Switzerland, where HTHP labs in this alchemic process make a diamond crystal. The diamond is sent home to Whistler, where it is cut and polished.
