Our Guide to Diamonds – Walker & Hall
By using the Gemmological Institute of America (GIA) grading, the quality of our diamonds are accurately and objectively determined for our customers on an internationally recognised level.
Our Diamond Guide will give you the knowledge and understanding you need when looking at and buying your very own diamonds. Evaluating their carat weight, clarity grade, colour scale, as well as the cut and shape of the stone, helps identify and differentiate between different types and specifications of diamonds.

The Four C’s
Cut
A diamond’s cut is not to be confused with it’s shape. It refers to both the outline shape and the proportions of the diamond. A diamond’s proportions affect it’s light performance which in turn determines it’s overall appearance and beauty.
Colour
The GIA colour scale ranges from D to Z and represents how noticeable colour (usually a yellow or brown tone) is in a diamond.
Clarity
Inclusions are a natural characteristic found in virtually all diamonds. The clarity grade reflects the impact of the inclusion on the appearance of a diamond.
Carat
The carat refers to the weight of a diamond, which correlates very closely to a diamond’s size.
