Difference Between Champagne And Cognac Diamonds

Difference Between Champagne And Cognac Diamonds

Chances are, you probably know that champagne and cognac diamonds may seem similar to the untrained eye. However, we want to help demystify this for you so that you can confidently choose which diamond is right for your needs.

What Are Champagne Diamonds?

They have a distinctive champagne colour, which means they differ in appearance from most other diamonds. This hue typically ranges from light pink to dark yellow-brown. Champagne diamonds are typically more expensive than white diamonds because their rarity makes them difficult to find and mine, so it’s important for you to know what you’re paying for when you buy one!

What Are Cognac Diamonds?

Cognac diamonds are a type of brown diamond that is gaining popularity for their deep hues and dark colour.  However, unlike champagne diamonds that have a touch of yellow in them, the colour of cognac can range from light to dark shades of brown, but it’s always deeper than champagne diamond colours. Cognac diamonds come from the same mines as champagne diamonds, but they just take on a different colouring and appearance due to their deeper and richer layers of soil.


While champagne diamonds are more expensive than cognac diamonds, they are not quite as rare. Their availability has led to a steep rise in their prices. While champagne diamonds have a lighter hue, cognacs are darker and brown. As such, they are the ideal choice for an engagement ring or a pendant.

If you’re looking for an unusual diamond, cognac diamonds may be the right choice. Its warm golden tones make it a gentler alternative to a colourless stone. Its neutral colour makes it ideal for both contemporary and timeless jewellery, and it is especially beautiful when paired with rose gold.

Price Difference

The price of these stones depends on some factors including carat weight, the intensity of colour, and clarity. A champagne diamond’s average price may range from $2000-3500, while a cognac diamond’s price may range from $2,200-6,000.

Refractive Index Difference Between Champagne And Cognac Diamonds

The best way to get a further understanding of the difference between champagne and cognac diamonds is by looking at their refractive index. The refractive index (RI) refers to how much light can pass through this stone, which will be different depending on what type of diamond it is. For instance, the refractive index of champagne diamonds may be slightly higher than that of cognac diamonds.

Do Champagne Diamonds Sparkle More Than Cognac Diamonds?

The answer is yes; champagne diamonds tend to sparkle much more than cognac diamonds do. Once again, this has a lot to do with their refractive index as well as how light can pass through the stone itself – white diamonds are typically very “see-through” whereas cognacs have lower RIs so they appear darker in comparison! This means that you will notice flashes of colour coming out of your champagne stones while there isn’t anything similar happening with your cognacs.

Champagne and cognac diamonds Australia and other countries have both tend to be fairly rare, although we want to point out that cognac diamonds are actually more so than champagnes. The reason for this is that these stones can only be found in a handful of places worldwide – they typically come from mines in Western Australia. On the other hand, you’ll find champagne stones all around Siberia, Australia, and Africa.

Cognac diamonds, also known as brown diamonds, are mined in Australia and can be found at Rio Tinto’s Argyle Mine. The Argyle Mine has pioneered the terms “champagne” and “cognac” diamond to help differentiate their stones from each other.

The Bottomline

In conclusion, it’s important to note that champagne and cognac diamonds aren’t truly different types of stones- rather they’re just variations on the same stone with slightly different features due to where they were sourced or what type was used during manufacturing. Both stones have their own unique benefits, so it ultimately comes down to personal preference when deciding which one is right for you!
