Of all the 4Cs, the cut has the greatest effect on a diamond's beauty and the only one not determined by nature. The diamond cutter's skill in fashioning the diamond will determine the grade of the cut. The cut is graded just like the colour and clarity, and is done by a machine and a mathematical formula. The GIA grade system is recognized worldwide with the top grade of Excellent or Ideal, Very Good, Good, Fair and Poor ratings.
Diamond with Excellent or Ideal cuts will have maximum fire and dispersion. Giving you the benefit of a brilliant, sparkling diamond.
If a diamond is cut too deep the light is lost out the side, if the diamond is cut too shallow the light is lost out the bottom. But if the diamond is cut to "Ideal" proportions the diamond will have total internal reflection which gives you the maximum sparkle, brilliance and fire.
Max Wilson Diamond Jeweller are diamond specialists and choose diamonds of the highest cut grades of ‘Excellent' and ‘Very Good'. A Max Wilson diamond is one of fire and brilliance and almost all of their diamonds come with either a GIA diamond certificate or a Quasar diamond certificate.
Diamonds come in a variety of colors, some of them highly prized (pinks, blues, even yellow). However in a white diamond, the presence of a yellow tint will lower the price of a diamond. The less body color in a white diamond, the more true color it will reflect, and thus the greater its value.
At Max Wilson Diamond Jeweller we use the GIA colour grading system. Many of these colour distinctions are so subtle as to be invisible to the untrained eye. But these slight differences make a big difference in diamond quality and price.
No two diamonds are alike. 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.'Under 10x magnification we look for any inclusions, mineral traces or fractures. The very best, and rarest clarity is internally flawless (IF) on GIA's scale, where IF and FL are the highest clarity, I3 the lowest.
Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how these affect the overall appearance of the stone. While no diamond is perfectly pure, the closer it comes, the higher its value.
Diamond weight is measured in carats. Diamonds and other gemstones are weighed in metric carats: one carat is equal to 0.2 grams, about the same weight as a paperclip. (Don't confuse carat weighed with Karat, as in 18K gold, which refers to the gold purity.
Because even a fraction of a carat can make a considerable difference in cost, precision is crucial. In the diamond industry, weight is often measured to the hundred thousandths of a carat and rounded to a hundredth of a carat. Diamond weights greater than one carat are expressed in carats an decimals (for instance a 1.08ct stone would be described as "one point oh eight one carat)
The round cut diamond is the most popular diamond shape, representing approximately 75% of all diamonds sold. Due to the mechanics of its shape, the round diamond is generally superior to fancy shapes at the proper reflection of light, maximizing potential brightness. However, diamonds can be cut in various shapes from the popular princess shape, to oval, pear, emerald, rectangular radiant, often referred to as the Fancy cuts.
