Posted: Nov 13, 2017
An objective standard of measuring the quality of an item is a necessity for maintaining a trust in the market. Diamonds were being sold without an established standard for centuries, however, this change with the creation of an institute called GIA (Gemological Institute of America). GIA started describing diamonds on four qualities, namely, color, clarity, cut, and carat. Since then these 4c's have established themselves as the global standard for checking the diamond quality. Therefore, before you make a purchase of loose diamond wholesale in UK, you must take these 4 checkpoints into consideration.
The highest grade is given to the diamond with no color. The diamond is able to produce white color only if it possesses chemical purity and structural perfection. Such a white diamond shines perfectly and looks like a drop of water. Consequently, such a diamond is given the highest grade, that is D. The color grading system of GIA moves from D to Z, with each increase in grade means an increase in the yellowish hue. The color distinction of the nearby grades are very subtle and thus are imperceptible to the untrained eyes but still, even a minor difference makes a huge impact on its price and quality.
The diamonds have a variety of internal characteristics called inclusions and external characteristics called blemishes. These inclusions and blemishes are formed during the formation of the diamond. During the evaluation of the diamond quality both the inclusions and blemishes are closely observed. The evaluator will consider the size, number, nature, position, and relief of both these characteristics. More importantly, the observer will see how these characteristics impact the appearance of the diamond. The GIA defines quality in 6 categories and each category is divided into specific grades. Before you buy loose diamond wholesale in UK, make sure to become acquainted with all the categories and grades of diamond clarity.
People generally think of diamond's cut as its shape but in the gem grading world, the cut means the ability of the diamond to transmit and sparkle light.

In general, the diamond that has proportionately and symmetrically cut and which has been polished perfectly will reflect light in a perfect manner.
