About Diamonds

Buying a diamond is a purchase most people make only a few times in a lifetime. Since this is such a rare and valuable purchase it is important that you have expert advice and guidance to help you to the correct choice.

Diamonds can be sorted into over 2000 categories according to size, shape, colour and clarity. Obviously this can be very confusing (even for us!), so to make everyone’s life easier these 2000 categories are condensed into 4 simple easy to understand headings known as “The Four C’s”: Cut, Colour, Clarity and Carat Weight.



This not only affects the visual shape – round, square etc but affects how bright the fire and sparkle are, due to the perfection of faceting or the cutters skill.



Most diamonds contain tiny internal marks known as inclusions. These are like natural birthmarks and can vary in size and concentration. They vary in form from tiny sooty spots to bubbles and internal fractures and affect the passage of light. Complete freedom from these inclusions is very rare and these are called FL (flawless). Most stones we select are around VS/SI very small/small inclusions though even these you will see only with a 10x lens.


In this aspect bigger is not always better. Other features all being equal a bigger stone will be more expensive, but a smaller stone could easily out-price a large stone which has been poorly cut and of poor colour and clarity. As larger stones are more rare this does affect price, double the weight for example will be far in excess of double the price providing all other features are equal.

1.00ct = 0.2g, 1.00ct = 100 points,
0.50ct = 50 points, 0.25ct = 25 points




The best colour for a diamond is no colour at all, however these stones are very rare and referred to as ‘D Colour’. The majority of stones fall below this anywhere down to Z and even into fancy yellows, pinks and browns.
