  1. Colour

The most perfect diamond is colourless. They are the rarest and the most expensive ones. Therefore, the colour of the diamonds is the degree of its colourlessness. However, the majority of the diamonds possess varying degrees of yellow or brown. It is extremely difficult to spot colour with an untrained eye. In fact, people without gemological training find it almost impossible to see the differences in the top 5-6 colours in the case of mounted diamonds less than 1/2 carat in weight.

This is the GIA colour scale which is the standard colour scale used to calibrate the colour of diamonds across the globe. The scale starts from D (Colorless diamonds) and goes to Z (light yellow diamonds). Here is a table which depicts the exact colour for each letter:

  1. Cut

The cut refers to the proposition of the diamond and not the shape of it. Cut affects the diamond’s light return properties known as fire and scintillation. The cut is the most important C of all C’s as it has the greatest effect on the beauty of the diamonds. Poor cut dulls the brilliance of a diamond no matter how perfect its colour and clarity is. 

  • GIA Cut Grades:

Excellent

Very GoodGoodFairPoor

 Excellent cut diamonds are the most brilliant ones as they typically have about 97% light return.

  1. Carat Weight

This is the weight of the diamond and determines the appearance and size of the jewellery. 1 carat is 200 mgs. 1 carat is usually subdivided into points or cents as most of the diamonds sold in the market weigh less than 1 carat. There are 100 cents in a carat. For example, if a diamond weights 3/4 carat, then it weighs 0.75 cents.

Knowing these 4 Cs is the key to purchasing the perfect diamond. This will help in using the Caratlane coupons on the right products.
