Highly sought after and highly prized, their colour is a result of exposure to radiation during their formation deep in Earth's crust for millions of years. Gamma rays or particles cause a change in their crystalline structure, creating color centers that absorb red and blue light, allowing primarily green light to be seen when one observes the stone. The colour green has long become associated with spring, vitality and fertility, with green diamonds taking on the symbolisim of new beginnings.
