The scale profiles more than 20 subtle grades of colour and identifies them in alphabetical order from D to Z, while comparing them to a master set of stones under controlled lighting and precise viewing conditions. Diamonds with colours that are outside the scale are known as "fancy colour diamonds."
Clarity refers to these inclusion features, which are determined by viewing diamonds under a 10-power magnification loupe. The amount, type, colour, size and position of the inclusions affect the value of a diamond. Fancy colour diamonds are purchased almost exclusively for their colour intensity and clarity is often disregarded.
Pandora jewellery uses diamonds that are classified as H/VS (Very Slightly Included) which means they have minor inclusions that are difficiult to somewhat easy for a trained grader to see when viewed under 10x magnification
The cut refers to the diamond's shape outline, but it can also refer to a diamond's faceting, proportion, symmetry and finish. A well-cut diamond balances brilliance, which is the return of white light from the diamond to the viewer's eye, dispersion, which is known as 'fire' and is the flashes of colour a diamond refracts, as well as scintillation, which is characterized as the sparkle seen when a diamond catches the light.
