We buy a wide range of diamond jewellery, including:
We assess the value of your diamonds using the ‘four Cs’ which is the standard method for grading all precious stones:
This refers to the diamond’s shape and symmetry, and how these affect how light enters and reflects within the stone. The more reflections, the brighter the diamond appears.
Clarity is about the number and size of internal flaws (inclusions) and surface imperfections (blemishes). Fewer imperfections mean a higher value.
While diamonds come in various shades, the whiter the stone, the higher its value. Yellowish tones suggest more impurities, thus reducing the price.
Carat refers to the diamond’s weight. Prices are calculated per carat, so the greater the weight, the more the diamond is worth. Please note that lab grown diamonds have a lower price per carat than natural diamonds.
