Diamond facts

A: The Four Cs stand for Cut, Colour, Clarity and Carat Weight. Every diamond is specifically graded on these four features. It is the industry grade standard from the Gemological Institute of America (GIA). Please visit our 4Cs page for more information.

A: Look for a good combination of the 4Cs: Cut, Colour, Clarity and Carat weight. The cut is the most important factor to consider, as this is determined by the skilled diamond cutter, and should not be compromised on. The cut will determine the fire, brilliance and scintillation of the diamond. The remaining 3Cs (colour, clarity and carat weight) are determined by nature.

A: The Ideal Cut diamond is based on a specific set of proportions for a round brilliant diamond, proposed by gem cutter Marcel Tolkowsky in 1919.

A: Yes. Diamond prices have been steadily increasing for the past decades and diamonds tend to hold their value.

A: Conflict-free diamonds are not obtained due to human right abuses, child labour, violence or environmental degradation. Diamonds 27 is committed to sourcing conflict-free diamonds from legitimate diamond sources who share our ethical philosophy and zero-tolerance policy towards conflict diamonds. Therefore, you can be assured that you are buying legitimate diamonds from a trusted diamond source. Visit our Conflict-free diamonds page for more information on this topic.
