Carat is a unit of measurement. As it increases, the more rare it is and the pricier it gets. One carat is equal to 200 milligrams or 0.2 grams to be exact.
Diamonds are made to undergo extreme pressure. The clarity of a diamond can be determined on the location and number of “inclusions” it has. This ranges from Fl or Flawless to -I3 or Included 3. Absolutely flawless diamonds are incredibly rare and definitely expensive.
Every stone is color-graded precisely from “D” (colorless) to “Z” (saturated). Totally colorless diamonds allow light to pass through easily and disperses like the color rainbow. Some may appear colorless in one’s naked eye but its impurities can give subtle hints of color that only the trained eyes of jewellers can notice.
