In a colourless (white) diamond Clarity is extremely important in assessing the value of the stone. However, in terms of Fancy Coloured Diamonds, the clarity grading is a minor factor in the valuation of the stone.
A diamond grading report indicates the carat weight to the nearest hundredth of a carat weight. Diamond pricing is often referred to by the price per carat as opposed to the overall cost of the stone.
The value of a diamond does not relate directly to the carat weight. In other words a 1.50 ct Diamond will not be exactly half the price of a 3.00 ct Diamond. In terms of value, the price of Diamonds increase exponentially as the carat weight increases.
The cut of a Diamond does not in itself have an immense effect in the valuation of the stone. However, the way in which a Diamond is cut does affect the other aspects of diamond grading. The manner in which the diamond is cut influences the carat weight. The proportions of the stone affect the diamond's colour. The polishing process assists in the removal of external blemishes and thus enhances the diamond's clarity.
In cutting and polishing a rough diamond, the intention is to derive the best possible finished product. Sacrificing carat weight can often strengthen the colour and clarity of a Diamond.
