Argyle Champagne Diamonds

Argyle Champagne & Cognac Diamonds Australia

More abundant than pink diamonds, Argyle champagne and cognac diamonds come in a variety of colours from light yellowish browns to rich chocolate and oranges.


The lightest and the most intense champagne diamonds are the more highly prized. The colour of a champagne diamond is caused by a colour centre, scientifically described as an atomic level lattice defect that absorbs and reflects light similar to the pink diamonds.

Previously lesser known, these stunning cognac and champagne diamonds were introduced to the wider market by Argyle Diamonds and they are now seen as some of the most desirable and noted Argyle diamonds.

Colour ranges vary greatly and Champagne diamonds are classified from the lightest C1 through to the most intense C7. At the C7 end, these diamonds are referred to as Cognac diamonds.

Our Argyle Champagne Diamond Ring in 18ct white gold was our January Design of the Month and features an impressive 1.84 carat certified Argyle champagne emerald cut diamond.

Solid Gold Diamonds holds one of the largest collections of Argyle champagne diamonds available to view in Australia.

Many of our Argyle champagne diamonds over 0.30ct are laser inscribed with “ARGYLE”.
