The universal method for assessing the quality of any diamond, anywhere in the world.
Diamonds are renowned for their ability to transmit light and sparkle so intensely. We often think of a diamond's cut as shape (round, emerald, pear), but a diamond's cut grade is really about how well a diamond's facets interact with light.
When a diamond is not well cut it allows light to flow through it without reflecting it back. When light percolates through the diamond either through the bottom or through the sides, the diamond’s fire is dampened and there by brilliance muted. Sometimes when the clarity and color of the diamond are superior and yet the diamond appears gloomy, it is most likely that the cut of the diamond is not superior.
Different Cuts of Diamonds: Do not confuse shape of a diamond to a cut of the diamond. Cut of a diamond refers only to the amount of light reflected back. Different kinds of cuts- Heart and Arrows, Excellent cut, Very Good cut, Good cut and Fairly cut diamonds.
The weight or size of a diamond is measured in carats (ct.)
A carat is 0.2 grams and there are 100 points (or 200 milligrams) per carat. Carat weight is not the same as karat of gold which refers to purity. Every carat can be divided into 100 cents and the size of the diamond is equal to the carat-weight of diamond. For example: Half carat diamond is also called 50 cents. Carat weight refers only to the weight of the diamonds and not to the dimensions of a diamond.
Most diamonds are white in color and diamonds are graded based on presence or absence of color. A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value. Diamond color is all about what you can’t see. Diamonds are valued by how closely they approach colorlessness – the less the color, the higher their value. (The exception to this is fancy color diamonds, such as pinks and blues, which lie outside this color range.) Most diamonds found in jewelery stores run from colorless to near-colorless, with slight hints of yellow or brown. GIA's D-to-Z color-grading scale is the industry's most widely accepted grading system. The scale begins with the letter D, representing colorless, and continues, with increasing presence of color, to the letter Z.
Natural diamonds are the result of carbon exposed to tremendous heat and pressure deep in the earth. This process can result in a variety of internal characteristics called 'inclusions' and external characteristics called 'blemishes.'
Diamonds usually contain flaws. These are also called inclusions. Usually only trained gemologists can determine the Clarity of a Diamond. The best diamonds are usually flawless. However, to find such diamonds is a rarity. Diamond buyers will sometimes choose a gem with some inclusions, as long as they are not visible to the naked eye.
The highest clarity grade is FL or IF. These stand for Flawless and Internally Flawless. These diamonds have no imperfections seen under 10 x magnifications.
The next two grades grouped together are VVS1 and VVS2. These diamonds are defined as Very Very Slightly Included. The imperfections in these are so tiny that even a trained grader might have difficulty locating the inclusions. They are usually a minor pinpoint or a few pinpoints as seen under magnification.
Next are the VS1 and VS2 clarity grades. These diamonds are defined as Very Slightly Included. Small pinpoints and feathers might be found in these grades but they are still small relative to the size of the diamond.
All our jewelery products are accompanied by genuine and valid certificate from an Independent international labs attesting to the quality of the stone used. The certification is an assurance of the quality of the diamond.

IGI Yet another standard, International gemological institute certifies diamonds based on the characters of the diamond. Grading the 4Cs of the diamond, grading them, makes this certificate a highly acknowledged one.
SGL: Solitaire Gem Labs (SGL) is an independent international laboratory that provides professional gemstone identification and grading services to the gems & jewelery industry worldwide through its centers in London, Dubai, Jeddah, Riyadh, Mumbai (Bombay), Bangalore, Chennai, Hyderabad, Thrissur, Coimbatore, Pune, Jaipur and Kolkata.
