Loose Champagne Coloured Diamonds Guide

Understanding Argyle Champagne Diamonds

Let’s firstly clarify what a champagne colour is…

It’s a very light brown, typically with a secondary tone of yellow. The tonal combination evokes thoughts of champagne, honey, and amber in a range of hues and saturation.

There are several causes for the brown colour, including irradiation treatment, nickel impurities and lattice defects associated with plastic deformation; the last is the predominant cause, especially in pure diamonds. A high-pressure high-temperature treatment can heal lattice defects and convert brown diamonds into yellow or even colourless stones.

Argyle Champagne Diamonds

The majority of champagne diamonds are unearthed from the Argyle Diamond Mine in the East Kimberley region of Western Australia. The Argyle Mine is responsible for producing a large percentage of the world’s coloured stones, including their signature pink diamonds.

Grading Champagne Diamonds Colour

You will never see the word “champagne” on a grading report from the Gemological Institute of America. Instead, the colour would be described as fancy light yellow brown, fancy yellowish brown, or a similar phrase that indicates the hue and intensity.

On the other hand, The Argyle Mine has devised a different colour scale specifically to grade champagne diamonds, which ranges from C1 to C7. C1 is the lighter end of saturation with C7 being the darkest.

+ How Rare Are They?

Natural champagne diamonds are quite abundant but can be difficult to find in fine cut qualities & light performance with a visual pleasing tonal range of colour (due to the mix of brown and yellow colouration).

+ Are They Expensive?

Now while it can be difficult to find options you would consider for selection, they are quite cost effective due to their more common rarity and market-demand.

+ Are There Alternate Gemstones You Can Recommend?

Due to the cost effectiveness of this naturally coloured diamond, it would certainly be the best choice for and engagement ring, wedding ring, or any piece of jewellery that was worn regularly. For more occasional pieces we would recommend considering Natural Zircon, Brown Tourmaline, as well as Brown Golden Beryl.
