Diamonds &
The 4 C's

Buying a diamond ring is a big investment both financially and emotionally, so when looking for the engagement ring of your dreams we aim to offer you the very best information and advice to help you make the perfect choice.

The quality of each diamond is determined by its cut, clarity, colour and carat known as the 4c's, helping to categorise each diamond and discover its beauty. 

1. Cut

It takes a painstaking amount of work, all by hand, to make diamonds so beautiful as they start out life in an uneven natural state called a ‘rough.’ Every other aspect of the 4C’s is an act of nature, however, the cut is the only part of diamond creation that requires human input. It’s the most important, yet misunderstood part of the process. Diamond cutting is an art which can take weeks to produce the perfect outcome.

Cutting is so important because it unlocks a diamond’s beauty and sparkle. A perfectly cut diamond will be staggering thanks to its brightness - how much light is reflected, fire - the rainbow effect created when light hits the surface and scintillation - the flashes of light created when the diamond moves. These are key in producing the perfect diamond engagement ring your fiancé-to-be will treasure forever.

2. Clarity

A diamond has the capability to refract more light than any other gemstone. One which is free of interior inclusions or exterior flaws has nothing to interfere with the passage of light through the stone and so is considered to be of the highest quality. Such stones are very rare and correspondingly expensive!

Most diamonds contain tiny natural marks called inclusions. The number of inclusions, their size and location all affect the diamond’s clarity grade. While it is true that the clearer a diamond, the better, minor inclusions will not compromise a stone’s beauty or endanger its durability.

3. Colour

The best colour for a diamond is no colour at all. These are known as 'white diamonds'. Other rare diamonds with a pure colour, such as pinks, blues or greens, are also valuable and are known as 'Fancies'. Colour grading scales from colourless to light yellow. The differences from one grade to another are very subtle, evidenced by the number of grades within each category shown on the International Colour Grading Systems Chart. Diamonds range from colourless - the rarest and most valuable - to yellowish, with a spectrum of shading in between.

4. Carat

Carat relates to your diamond’s weight. One carat is equal to a fifth of a gram. Two diamonds with the same qualities will differ in value as they diverge in weight because of the rarity of heavier stones. George Banks carry beautiful diamonds in a range of carat weights.
