Colour and carat
The rarest colours are the pronounced and vivid hues of orange, pink, green, blue…These rare varieties are called ‘fancy’ colours and are often less suited as investment diamonds. The market for these kinds of diamonds is rather small because of their high price point, which means that both the purchasing and selling of these diamonds will be a time-consuming process. Almost all colour hues between white/ colourless and fancy yellow, however, are suitable as investment diamonds.
Carat is the weight unit for diamonds. 1 carat equals 0.2 grams and is expressed in 100 points. The correlation between carat and price is exponential, because the higher the carat weight, the more unique a diamond is. An investment diamond of 3 carats is not three times, but five times more valuable than a diamond of 1 carat. The most accessible and best investment is thus a diamond with a white or yellow colour, with carat weight up to 2 carats.
