The Four C’s
Here is some information that I like to pass on to all my clients:-
Cut – This refers to the shape of the diamond – i.e. round, princess, emerald, heart etc. Also it refers to how well-proportioned the diamond is and how the light enters the stone and reflects back. A well cut stone will sparkle more and attract a higher price than one that is graded poorly. If the stone has a certificate, then this is shown in the Grading Results and Finish details as excellent, very good or poor.
Colour – Talking about white diamonds. A white or colourless stone will be rated from D (which is colourless) to Z (a light yellow). The colourless D, E and F range are the highest in brilliance and price.
Clarity – Every diamond has a clarity rating. Inclusions are internal naturally occuring flaws, surface blemishes, feathering or fractures. A flawless diamond has no naturally inclusions and is the most expensive. Next on the list is the Very Very Slight Inclusions of 1 or 2, then Very Slight Inclusions of 1 or 2, then Slight Inclusions of 1 or 2, then Imperfect. The Imperfect clarity means that the inclusions are visible to the naked eye and the price difference is considerable compared to the Flawless stone.
Carat – Diamonds are weighed in Carats (which is equal to .2 grams). One carat is divided into 100 points, i.e. .50 pts, .75 pts. The value of a carat changes with the individual weight of each stone, cut, colour and clarity.
Its better to keep up on the top FOUR colours and not go below Slight Inclusion of 2. A diamond never changes it colour and is a life long purchase to be considered seriously. It’s better to go for a smaller diamond higher in colour and clarity than a larger one on the lower side of the scales. Bigger isn’t always better in the case of choosing a diamond.
