WHITE DIAMONDS

Subtle differences in a diamond's colour can dramatically af­fect it's value. Two diamonds of the same cut, clarity and weight can differ in value based on colour alone. A colourless diamond is more highly valued than one with visible colour. The cut of a diamond essentially determines its sparkle, professionally known in the industry as brilliance. 

The formation of diamonds happens in the earth, over millions of years and under extreme heat and pressure. Because of such conditions, each diamond comes with natural marks or imperfections within it, and these marks are better known as inclusions. This natural process ensures that no two diamonds have the same inclusions, so the clarity of a diamond is what makes each one truly unique.

Duchess Diamonds is proud to offer the highest quality white diamonds for your next investment piece.

COLOURED DIAMONDS

Deep blues, rich reds, and glorious greens are the rare and expensive colors that make up the rainbow of what are often called “fancy coloured diamonds.” More affordable, and quite beautiful yellows, oranges and even chocolate browns are also desirable choices. If you love the sparkle and brilliance of diamonds and love the hues of gemstone's like rubies and emeralds then you would certainly love coloured diamonds!

You can select from our vast range of coloured diamonds and customise any jewellery design to have your own unique piece of luxury. Coloured diamonds are worn by royalty, aristocrats and celebrities alike.

GIA’s nine-tiered rating system for colour ranges from Faint to Fancy Vivid. The “origin of colour” of a coloured diamond (that is, whether it's colour is natural or laboratory-treated) is disclosed on a GIA Grading Report.
