Of the fancy coloured diamonds Champagne coloured diamonds are the most commonly found and therefore do not command the very high prices that other rare fancy colours do. This fact makes them a very good option for those who like the colour and would like to gain some additional size for the budget to hand.

Cognac Diamonds.

Cognac diamonds are rarer than the Champagne colours and therefore tend to be a bit more expensive, weight for weight. The C1 -7 grading scale puts them from C5 – C7, with C7 being a very dark burnt orange brown and highly prized for those who favour this colour type.

The terms “Champagne”, “Cognac” and “Chocolate” were created by the Argyle mine as a marketing tool to promote the diamonds in which they are large producers. This campaign helped greatly to the awakening the world to the beauty of these gems.

Champagne and Cognac diamonds have been used in jewellery since early Roman times, but in the modern day and age they were largely used for industrial purposes only. This was a great shame, as they are truly beautiful diamonds. This is especially the case when set against high colour white diamonds as in the rings above.

These days consumers have come to appreciate the intrinsic beauty of the stones, and Argyle does not need to promote them for use in jewellery so much any more.  Champagne and Cognac diamonds are especially popular in the US, where a whopping 40% of Argyle’s sales in these colours occur. They are also becoming increasingly popular in China and India for engagement, dress rings, pendants and earring.
