Champagne diamonds, also known as dark diamonds, brown diamonds or chocolate diamonds, are delectable stones that come in a smorgasbord of brown hues.
Champagne diamonds are naturally occurring phenomena and are prominent across the globe. Australia, Africa and Siberia are home to the most exquisite diamonds of this kind. The Australian Argyle Diamond Mine is the largest champagne diamond producer and exporter.
While the 4 Cs – color, cut, clarity and carat – still apply to champagne diamonds, their color is their most exquisite and prized feature.
Argyle Diamonds created a scale to assess the quality of a champagne diamond’s color.
The color scale ranges from C1 to C7. C1-C2 are considered light champagne colors, C3-C4 are medium colors, C5-C6 are dark colors, and the darkest hue is C7, formally known as a cognac color. Cognac diamonds are the rarest and most expensive champagne diamonds.
Gemologists look at three features of a champagne diamond’s color.
The hue of the stone is the supreme brown color of the diamond.
They will also assess the diamond’s tone, or the warmness or coolness of its undertones.
Finally, gemologists look at how concentrated, or saturated, a diamond is by gauging the intensity of its brown color.
Like colorless diamonds, champagne diamonds are prone to inclusions and blemishes. Blemishes are minor imperfections (e.g. a thin cut) that are on the surface of the stone.
In contrast, inclusions are imperfections that affect the atomic structure of the diamond (e.g. discoloration) and they are more difficult to repair and disguise.
Champagne diamonds can be graded Internally Flawless to Included.
The cut of a champagne diamond is important because it reflects its brightness, fire and scintillation. Round cuts tend to be the standard ones for the most bling.
The weight scale and attributes of normal diamonds also apply to champagne diamonds. One carat is the equivalent of 0.2 grams, or 100 points.
Like colorless diamonds, heavier champagne diamonds (e.g. those around 5.00 carats) are highly desired and expensive.
