International Standards


The diamond's quality, and therefore its value, is set by what are called the 4Cs. These relate to: carat, color, clarity and cut which decide the price of the gem.


Features

  • Carat - Diamonds are weighed in carats, with 1 carat equaling 0.2 grams.
  • Color - Diamonds come in a wide range of colors, ranging from colorless to yellow.
  • Cut - Determines how light entering the stone will react and how much light return.
  • Clarity - Refers to the purity of the diamonds or to the degree that it is free of inclusions.
