Diamonds are valued using the Four C's: Carat, Clarity, Colour and Cut. We've given you a full outline of what these mean below. Where we use white diamonds above 5mm in size, we can supply a GIA certificate if requested. Please make us aware if you require a certificate.
The size of a diamond is measured by carat weight. A one carat (1ct) diamond equates to 100 points, so a 1/2 carat (.50ct) equals 50 points. We do our best to quote the carat content for all our designs. This is detailed in the product description.
The clarity of a diamond measures the degree to which a stone has inclusions. Most natural diamonds will have small inclusions. Where we specify white diamonds, we use VS1 clarity and above.
Diamonds are graded in colour from D (colourless) to Z (deeper colour). Where we specify white diamonds, we use colour G and above. We also often use brown diamonds for their beautiful natural colour. You will see these identified as champagne, sherry or cognac diamonds.
The precision and proportion of a diamond cut affect it's brilliance and sparkle. Below is a chart of the standard cuts for white diamonds. We also use more unusual and 'antique' cuts - particularly rose cut diamonds and Indian 'polka' sliced diamonds. The cut of the diamonds we use are identified in the product description.
