Diamonds can be classified according to the 4 Cs – cut, colour, clarity and carat weight. The combination of these four factors determines the value of a diamond. All centre diamonds used in our engagement rings are GIA certified, individually sourced and hand set to ensure the highest quality. Cassandra Mamone only sources diamonds above SI1 clarity and above F colour.

Our Diamonds
Cut
While diamonds come in different shapes, the term “cut” refers to proportion. When a diamond is cut to exact proportions, neither too deep nor too shallow- light will reflect inside the stone from one mirror-like facet to another and reappear through the top of the stone, making it sparkle from within.
Colour
Cassandra Mamone selects colourless diamonds from the top 3 colour grades D, E, F- these are the most rare, therefore the most valuable. Coloured Fancy diamonds are an exception, and are also very much sought after due to their extreme rarity.
Clarity
Nearly all diamonds contain tiny marks, which look like tiny crystals, clouds or features when viewed under magnification.
Diamonds exhibiting no inclusions are categorised as flawless (FL) or internally flawless (IF). Cassandra Mamone sources beautiful diamonds above the clarity of SI1 (Slightly Included). The fewer and smaller the inclusions, the more valuable a diamond will be.
Carat Weight
A diamond’s size is measured in carat weight. One carat is equal to 0.20 of a gram or one-fifth. Each carat is divided into 100 points so a diamond of 50 points weighs 0.50 carats.
