The shape of a diamond is simply how the stone looks. Shapes refer to the
appearance, which can range from round, princess and pear to cushion,
marquise, oval and emerald. Knowing the shape of your diamond can help
determine the perfect style, cut, and clarity for you.
Most diamonds have color in them. The center stone is usually made of a white diamond, but diamonds come in other colors such as, blue, yellow, pink, brown, red, and green. These colorful gems are rare and more often than not, cost more than the colorless diamond.
Cut is all about proportions and angles of the diamond. A finer cut diamond will reflect more light.
Carat weight is simply how much the diamond or gemstone weights. A diamond can seem larger or smaller than it really is.
There are many grades between flawless and imperfect. From blemishes to inclusions, the clarity of a diamond determines the exclusivity.
The first step is to weight and measure the diamond. This can be achieved with an optical scanning device. This will get the most accurate measurements. Ultimately you want both precise measurements and proportions of the diamond.
The clarity of the diamond is determined by magnifying the damond.Examine the diamond for any blemishes or inclusions that may not be visible to the naked eye. Blemishes are flaws found on the surface and inclusions are flaws on the inside of the diamond. The grader will then determine the size and characteristics of each blemish. This process is done three times by three different grades to achieve accurate results.
Each diamond is then compared to different stones ranging on the color grade scale from d to z. Ultimately, you want to see where the diamond would fall in the color spectrum. The diamond also goes under a UV light to determine fluorescence. This process is also done by several people.
At the end of the process, the diamond’s fluorescence is determined and added to the grade score. The final grade includes the measurement, proportion, and clarity of the diamond.
