Carat Weight

Carat is the unit of measurement used to describe a diamond’s weight and is equal to 0.2 grams. From perfectly proportioned stones of less than one carat to extraordinary gems weighing over 100 carats, each Graff diamond is a true masterpiece.

Colour

The most highly regarded white diamonds are completely, or close to completely, colourless. Colourless diamonds are graded from D, at the top of the scale, through to Z, with the majority of Graff diamonds ranging from D to G.

Clarity

Clarity measures the number, size, position and colour of inclusions captured within, and blemishes on the surface of, a diamond. Graff diamonds are exceptionally pure; many are Flawless or display minute inclusions that are invisible to the naked eye.
