Technically, diamond is the hardest mineral composed almost entirely of carbon molecules.
Its strength and durability also make diamonds useful for industrial application as excellent abrasive.
It requires high-pressure exposure of carbon-bearing materials in the lithospheric mantle below relatively stable continental plates or due to meteoric strike impact thousands of years ago.
A quality diamond may be colorless or occur in any hue including the non-spectral hues of gray, brown and black.
Color diamonds may be affected by chemical impurities and/or structural defects and depending on the hue and intensity of a diamond’s coloration.
A diamond’s color can either decrease or enhance its value.
Most white diamonds are sells in discount prices when detected a yellow hue in it, while a color diamond with intense pink or blue diamonds can be dramatically valuable
The majority of diamonds found in a range of pale yellow to brown color that is termed the normal color range.
Diamonds that have intense yellow or brown, or any other color are called fancy color diamonds.
They get their fancy color as an impact of presence trace elements.
Nitrogen creates yellow to orange shades, boron creates blue or grey, the presence of hydrogen makes unique violet.
The tremendous pressure exerted on a diamond deep in the earth can abnormally compress its structure, thus creates a red, pink, purple or brownstone.
And the impact of varying quantities of natural radiation creates blue hue.
Because natural color diamonds are very exceptional and can be quite expensive, diamond treatments are common and make it more possible to own a color diamond.
Gemologists create fancy color diamonds by manipulating less desirable diamonds to alter their colors.
Irradiation, followed by high heat treatment, can turn brownish and pale yellow diamonds into richly colored, affordable gems.
Therefore make sure you have a lab certificate to verify the authenticity when decided to buy natural color diamonds.
