Diamonds grading system based on the concept of the four C’s: color, cut, carat, and clarity. Clarity is determined by placing the diamond under 10X magnification. With the proper cut, the diamond will sparkle. Clarity and color are next in importance. All other gemstones grade with the naked eye.

The quality of all wholesale colored stones based on the clarity and brilliance of the stone’s color, which divided into three parts: hue, saturation, and tone. Hue refers to the stone’s color, which produced in the following spectral hues: red, orange, yellow, green, blue, violet, purple and pink. Purple and pink are spectral hues, as purple lies halfway between red and blue, and pink is really a lighter shade of red. Natural stones seldom have pure hues, so these are into primary, secondary, and sometimes tertiary hues. Saturation refers to the clarity of color, or the stone’s freedom from brown or grey hues.

Diamonds occur in a variety of colors — steel gray, white, blue, yellow, orange, red, green, pink to purple, brown, and black, virtually in every color of the rainbow. Colored diamonds contain interstitial impurities or structural defects that cause the coloration, whilst pure diamonds are perfectly transparent and colorless.A chemically pure and structurally perfect diamond is perfectly transparent with no hue, or color. However, in reality almost no gem-sized natural diamonds are absolutely perfect. The color of a diamond may be affected by chemical impurities and/or structural defects in the crystal lattice. Depending on the hue and intensity of a diamond's coloration, a diamond's color can either detract from or enhance its value. For example, most white diamonds are discounted in price when more yellow hue is detectable, while intense pink or blue diamonds can be dramatically more valuable. Out of all colored diamonds, red diamonds are the rarest. The Aurora Pyramid of Hope displays a spectacular array of naturally colored diamonds, including red diamonds.

Diamonds occur in a variety of colors — steel gray, white, blue, yellow, orange, red, green, pink to purple, brown, and black, virtually in every color of the rainbow. Colored diamonds contain interstitial impurities or structural defects that cause the coloration, whilst pure diamonds are perfectly transparent and colorless. Diamonds are of two main types and several subtypes, according to the nature of impurities present and how these impurities affect light absorption.
