Stone Guide
In order to assess the value of diamond jewelry it is very important to understand the standards of diamond valuation. Basically there are four standards to compare and evaluate diamonds: Cut, Color, Clarity and Carat.

Cut – It refers to the proportion and arrangement of facets in a diamond. Amount of, brilliance, sparkle and fire is determined by the cut. A Scale is used to rate a diamond’s cut, which ranges from excellent to poor. In excellent cut diamonds light is reflected from one facet to another and then dispersed through the top of the stone, whereas in poor cut diamonds light escapes through the bottom or sides of the stone.

Color – It refers to the lack or absence of color. The more clear or transparent a diamond is the more valuable it is. Most diamonds appear colorless, but have tints of yellow or brown color. They are graded on a color scale from D (colorless) to Z (heavily tinted). The differences between one shade and the next is very slight, so grading is done under controlled lighting, using a master diamond sample set for comparison and accuracy. Natural diamonds also occur in shades of blue, green, yellow-orange, pink, red, and even black, which are extremely rare and valuable. They are graded according to the intensity of their color.

Clarity – It refers to the presence of internal inclusions or impurities and external blemishes in a diamond, which can be viewed using 10X magnification. Inclusions can be in many forms like white points, dark dots or feathery cracks. These inclusions were developed within the diamond while it was being formed. Clarity depends on Number , Type, Size and Placement of inclusions. It ranges from flawless which has no imperfections to included which has significant Number of inclusions.

Carat – It reflects the weight of a diamond and not its size. One carat equals to 1/5 of a gram. Carat is subdivided into 100 equal parts called as ‘Points’. For example if a diamond weighs 0.30 carats then it is referred as ’30 pointer’. Diamonds with larger carat weight are more valuable than lower ones. However, pricing of a diamond is affected by other three factors also.
