These are atoms that aren’t part of a diamonds essential chemistry, some of these atoms can influence a diamonds colour and shape. . Nitrogen within a diamond can cause fluorescence and the yellow colour in a diamond, Boron within a diamond a diamonds atoms will make blue diamonds.

Treatment  Techniques for modifying a diamonds colour range from a simple coating to more complex combinations of heat and pressure. Diamond colour can also be induced by artificial irradiation and controlled heating called annealing. All diamond colour modifications are vulnerable to heat, to be safe never use a torch or other heat source near a coloured diamond .

Inclusions  Few things in nature are absolutely perfect, this is as true with diamonds as anything else. There are many different natural characteristics that occur in diamonds, inclusions can become part of a diamond during formation or as a result from its crystal structure. The effect that the different characteristics have on a diamonds clarity grade depends on their visibility at 10 x magnification. Inclusions that are enclosed within a diamond are typically crystal, needle, pinpoint and cloud. Enclosed inclusions as a result from the crystal structure are generally internal graining, twinning wisp or grain centre. Inclusions found on the surface of a diamond can include a cavity, feathering, chip or knot.

Interesting Facts  One ton of rock is mined to get less than 1/2ct of rough diamond. Typically only 5-15% of diamonds mined are fit for gem quality and the remainder are classed as near gem quality and industrial quality , which are used for industry tools. Diamonds are graded using GIA’s  4’Cs which stands for Cut, Clarity, Colour and Carat. The largest rough diamond mined was in 1905 and weighed an impressive 3,106ct! Named the Cullian Diamond. Diamonds are said to be the symbol of innocence and constancy.
