Guide To Loose Argyle Cognac Diamonds Or "Champagne Diamonds"


Understanding Argyle Champagne Diamonds

The tonal combination of Argyle cognac diamonds or champagne diamonds inspires thoughts in shades of champagne, honey, and amber in diverse levels, tones, and saturation. The colour of cognac diamonds is dark brown, typically with secondary hues of yellow and sometimes mixed with undertones of golden orange. Several reasons are associated with the argyle champagne diamond’s brown colour; one is due to champagne diamonds having nickel impurities. Natural irradiation is also a factor in creating the distinctive brown colour of argyle cognac diamonds, however, the most common cause is lattice defects associated with plastic deformation; especially in pure diamonds.

Argyle cognac diamonds, refined and worldly, symbolise sophistication. When set on a piece of jewellery such as a stunning argyle champagne diamond ring, you will most definitely be the talk of the town.

How Do You Grade Champagne Diamonds?

Champagne diamonds are graded on a fancy diamond scale, from C1 to C7. To classify champagne diamonds, Argyle Mine created a different colour scale for such gemstones. C1 is the lightest side, with C7 being the darkest. Specific standards within the industry determine the colour and quality of the diamonds. As specified in an industry-standard cognac diamond colour chart, colour also varies according to intensity. For champagne grades, grades C1 and C2 are light champagne, C3 implies medium champagne, C5 and C6 means fancy dark champagne colours. The colours of C7 graded champagne jewellery are the darkest. Typically, independent laboratories such as GIA grade the brown diamonds range in fancy light yellow-brown, fancy yellow-brown, deep orange-brown, and fancy darker orange-brown diamonds. If you are searching for that unique fancy cognac diamond, Certified Diamond Network is here to help. Arrange an appointment at our Parramatta store to view our extensive range of loose champagne diamonds for sale while receiving expert advice.


The better the cut, the more attractive the argyle cognac diamonds are. Generally, the champagne diamond price per carat is more cost-effective too. But unlike colourless diamonds, there are no standard cut proportions. If the cut appears richer in hues and brighter, the champagne diamond looks more appealing. However, in darker champagne gemstones, the brilliance is less, so white sunlight reflection is less noticeable. A poorly cut champagne diamond can at best look uneven or present no brilliance, eventually leaving gemstones dull and lifeless. The unique combination of carat, colour, clarity, and the diamond cut for each selected diamond is reflected in the cognac champagne price.


Champagne diamonds are light or dark brown and can have a secondary colour like pale yellow or orange-brown. The Argyle Mine closed on 3rd Nov 2020, had its own grade system for champagne argyle cognac diamonds, while the AGS carries a different diamond scale. GIA uses no Champagne word on report grades. Because it’s difficult to see how a champagne diamond looks, our experts recommend a second opinion which is another excellent excuse to engage with the team at the Certified Diamond Network if you need to determine a cognac diamond value and its legitimacy. It’s better if you’d catch a poor investment beforehand whenever possible. Unlike a white diamond used in asolitaire ring, champagne diamonds or brown diamonds are more eye-catching. Champagne diamond engagement rings will stand out among other rings and stones regardless of size or cut.


The clarity of stones determines how clear they are of imperfections and inclusions. The fewer faults, the better the quality of the stone. Many champagne diamonds are eye-clean at grades between Si1 to Si2’. However, champagne and brown diamonds of the VS class can be found at a very reasonable price as well. Like any colourless diamond, champagne or brown diamond is classified on the same scale. It’s sometimes difficult to appreciate the cut of a champagne diamond from the lowest end of the scale with the naked eye. The team at Certified Diamond Network are here to help! If you are looking for eye-catching bespoke cognac diamond rings, Australian buyers swam to look no further.


Generally, champagne diamonds will cost less than an equivalent colourless diamond of the same cut quality, clarity and carat weight. So, a champagne diamond ring can be an excellent investment if you want an affordable diamond yet highly unique. Are you are looking to buy loose champagne diamonds?

What Metals Complement Brown Diamonds?

The Argyle Champagne brown diamond is characterised by an earthly brown hue and a subtle honey tint. The higher the level of lattice defects there is, the darker and more vibrant the gemstones become.

Most commonly, brown diamonds work well with rose gold or yellow gold. The contrast between the stones and the location of metal tones is an important design consideration. White gold and brown diamonds create more powerful differences and bolder looks. White gold metal complements brown diamonds because it emphasises the richness of the brown hue with a neutral colour. Platinum is another metal that complements brown diamonds well. It highlights their colour and brings out all of its subtlety. The transition from stone to metal is more fluid. This colour will also enhance your diamond colour and size.

Champagne diamonds are brown coloured diamonds with a noticeable yellow tint, which is sometimes the result of treatments used to enhance their natural tone and colours. They range in colour, tone, and hue, with a glassy or metallic lustre.

Typically, cognac diamonds have more depth. Unlike regular white diamonds, champagne diamonds are proportioned this way to retain more of their natural body colour. Because they’re so minimalistically pure and understated, cognac diamonds suit the tastes of those who want elegance with an earthy edge. Chocolate diamond has a different colour, tone, hue, and intensity.


A 1 carat champagne diamond price can vary depending on the quality, weight, tone, hue, and intensity. Prices are determined based on three factors: rarity, light performance, and designer luxury status.
