Diamond Education

Diamonds are graded by four main characteristics known as the 4C’s, which directly impact the price of a diamond.

COLOUR

In general, the highest quality diamonds are totally colourless, whereas lower colour diamonds can often have a slight yellow tint. Diamond colours are measured using a scale from D to Z, ‘D’ being colourless and Z being tinted yellow. The most popular colours range from G-K as these colours when set in an engagement ring or any piece of jewellery still have the visual effect of being a ‘white’ stone and you would get a lot more value for money.

CLARITY

Diamond clarity is the existence and visual appearance of internal characteristics of a diamond called inclusions; some inclusions may be white and some will be black specs usually only visible with a diamond loupe. If you cannot see the flaws with the naked eye it’s called an “eye clean diamond”. As long as a diamond is eye clean the inclusions don’t really matter, I refer to them as tiny beauty spots making the diamond even more unique. If you compromise slightly on the clarity you can spend a bit more on other more noticeable aspects of the diamond.

CARAT

A carat is a unit of measurement and is used to specify the weight of a diamond. ‘Carat’ is a diamond industry ‘special’ word for the weight of a diamond. Each carat (1.00ct) is subdivided into 100 points; so a jeweller may refer to a diamond that weighs 0.20 carats as ‘’20 points’’ which would mean 20/100.

CUT

For many people the cut is the most important aspect. We often think a diamond cut refers to the shape of a diamond but a diamond’s cut grade measures how all the dimensions of the stone interact to produce a visual effect. The cut of the stone is what gives a diamond its sparkle, fire, and brilliance. A poorly cut stone will look either dull, dark or transparent like glass. Getting a well-cut diamond has a huge impact on appearance, which is why it is typically referred to as the most important of the 4Cs.
