We assess the value of your diamonds based on the four Cs used to grade all precious stones.
This refers to the diamond’s shape and symmetry, which impact how light enters and is reflected inside. The more times it is reflected, the brighter the stone appears.
This refers to the quality of the diamond, its visual appearance including how many inclusions or imperfections there are, and the number of surface defects known as blemishes.
Diamonds vary in colour, however the whiter the diamond, the greater its value. If a diamond appears more yellow, this means it has more impurities which lowers the value.
Carat refers to the size of the diamond. Diamond prices are calculated as a price per carat, so the higher the carat weight, the more the diamond is worth. Please note that lab grown diamonds have a lower price per carat than natural diamonds.
