Coloured Diamonds
Coloured diamonds are among the rarest and costliest gems found. Coloured diamonds can show colours across the spectrum from pinks, greens, yellows and blues to a combination of different colours mixed together.
What makes coloured diamonds so special?
While white diamonds may be considered rare, coloured diamonds are so atypical and uncommon that it is extremely unlikely that you could ever find two coloured diamonds exactly the same- giving each stone a true uniqueness.
Coloured diamonds are graded on their colour and intensity. Clarity is not such an important factor as it is in white diamonds. The stronger the intensity the more expensive the diamond will be. For example, when pink diamonds are being graded, the result and hence cost will be dependant on the depth and intensity of the “pink” colouring, rather than the clarity (or internal cleanliness) which is a significant factor in grading white diamonds. The Gemological Institute of America (GIA) uses nine different grades for the intensity in coloured diamonds.
