Cut : Diamond Cut is how well a diamond is cut and polished, including how well-proportioned the stone is, its depth and symmetry. Diamond Cut doesn’t refer to the shape of the diamond, such as an Oval or Pear Shape. Cut quality directly impacts the diamond’s beauty and brilliance. A well cut diamond is luminous and reflects white and colored light back to your eyes. Clarity : Clarity refers to a stones relative position on a flawless-to-perfect scale. Clarity characteristics are classified as inclusions (internal) or blemished (external). The size, quantity, position, nature, color and relief of the characteristics determine the clarity grade. Color : Grading color in the normal range involves determining how close a stone’s color approaches colorlessness. Most diamonds have a trace of yellow or brown body color, with exception of some natural fancy colors, such as blue, pink or red. The colorless grade is the most valuable. Carat Weight : Carat weight and the physical size of a stone vary between species of gemstones. For example, a carat round diamond is 6.5 millimetres in diameter, but a 1 carat ruby is 5.5 to 6.0 millimetres in diameter. This is because rubies are denser and typically cut heavier than a diamond. So, a 1.5 carat stone may be needed to replace the mounting of a 1 carat diamond. Physical measurements rather than carat weight should be used to match size. Colorless synthetic diamonds produced by Chemical Vapor Deposition (CVD) CVD diamonds are real diamonds. Although grown in a lab, CVD diamonds are gem-quality diamonds that have the same elemental structure and the same physical, chemical and optical properties as their natural counterparts. CVD diamonds are identical to the mined diamonds that have to be excavated from the ground. CVD diamonds are atomically identical to mined diamonds and are composed of pure crystalline carbon. The CVD process allows carbon atoms to attach to the seed diamond layer by layer. This produces a beautiful, genu
