- Deep Cut
- Shallow Cut
Diamond cut refers to the shape and proportions created when transforming a rough diamond into a polished diamond. A well proportioned diamond brings out the maximum beauty. Diamonds cut too deep or shallow lose light through the side or bottom, resulting in loss of brilliance.
Clarity is the degree to which a diamond is free from inclusions and blemishes, which can affect the flow of light as it passes through your diamond.
Like people, diamonds have natural 'birthmarks' that can vary in size shape position quantity and colour.
These 'birthmarks' or inclusions and blemishes are formed deep in the earth during the diamond growth.

At H.Samuel, we use the International Grading Scale developed by CIBJO (International Confederation of Jewellery Silverware & Diamonds).
Diamonds are graded using 10x magnification. The higher the diamond falls on the scale (above) the clearer it is.
- Diamonds that have very, very sight inclusions, are graded VVS₁-VVS₂ and inclusions can be difficult to see.
- Diamonds that are very slightly included are graded as VS₁-VS₂.
- Diamonds that are graded SI₁-SI₂ feature only slight inclusions which may or may not be visible to the naked eye.
- Any diamond hat has inclusions that is visible to the naked eye, are I₁-I₃, although I₁ will have fewer inclusions than I₃
Though nearly all diamonds have inclusions and blemishes the most prizede diamonds are flawless. Light is able to flow uninterrupted in a flawless diamond in beautiful sparkle.

Fancy colour diamonds aside (yellow pink, brown, blue), the best, most beautiful colour for a diamond is no colour at all. The closer a diamond is to having no colour, the more valuable it is.
At H.Samuel we use the GIA (Gemological Institute of America) scale of colour to measure diamond colour, ranging from D (colourless) to Z (light yellow).
A diamond carat is a measure of its weight not size and is measured in increments called points. One carat is equal to 100 points. Two diamonds of equal weight can have an unequal value depending on the cut clarity and colour of each.Please note - the carat weight images shown above are only a guide, variations in monitors will affect the actual size of the diamond
