Before buying a diamond there is a set of assessment guidelines that may help you.
At Dulong, we use the famous four Cs in order to assess our diamonds. The wellknown four Cs stand for Cut, Colour, Clarity, and Carat.
In addition, Dulong has expanded the assessment scale with two extra Cs, which stand for Confidence and Charisma.
