What’s the difference between black diamonds and white diamonds?
Diamonds are carbon based crystals, which were formed under great pressure from organic or inorganic carbon. Typically diamonds were formed far underneath the earth’s crust and brought to the surface by means of volcanic activity. It is also believed that the impact of an asteroid can form diamonds as a result of the impact with the surface. The formation of diamonds is believed to be approximately 3 to 4 billion years ago.
A diamond reflects and refracts light in similar fashion to a prism, which accounts for the fire-like flash and sparkle characteristics. Diamonds are not all typically the same colour, however the most valuable diamonds are considered to be the white variety. Diamonds considered less valuable can be treated with heat or radiation to darken the colour or improve its uniformity. In this way any diamond can be made to appear dark or even black.
