    Frequently Asked Questions

    What are natural champagne diamonds?

     
    Natural champagne diamonds are authentic diamonds formed deep within the earth that exhibit warm brown to golden-honey hues. Their captivating colour is naturally caused by trace amounts of nitrogen trapped within the crystal lattice during formation billions of years ago. Unlike treated stones, natural champagne diamonds possess an organic, untouched beauty that provides an elegant, warm alternative to traditional colourless diamonds.

    What makes natural Australian champagne diamonds unique?

     
    Australian champagne diamonds—most famously unearthed from the Argyle Diamond Mine in the remote East Kimberley region of Western Australia—are renowned worldwide for their exceptional character and fire. The unique structural composition of Australian stones often gives them a richer saturation and distinctive lustre that cannot be replicated, making them a proud symbol of Australia’s remarkable gemstone heritage.

    How are champagne diamonds graded on the colour scale?

     
    Champagne diamonds are graded on a dedicated colour scale developed by the Argyle Diamond Mine, running from C1 to C7 - in fact, the name 'champagne' was coined by Argyle in the 80's. (Prior to this, they were just called 'browns':

    • C1 – C2: Light Champagne (soft, subtle straw hues)
    • C3 – C4: Medium Champagne (warm golden tones)
    • C5 – C6: Dark Champagne (rich, intense amber and caramel)
    • C7: Cognac (deep, rich reddish-brown)

    This standardised scale helps you easily select the exact depth of colour and character you desire.

    Are champagne diamonds less expensive than white diamonds?

     
    Yes, champagne diamonds are generally more accessible in price than colourless (white) diamonds and significantly more affordable than ultra-rare pink or blue diamonds. However, their value continues to appreciate, especially since the closure of the Argyle mine in 2020. Larger carat sizes, high clarity grades, and deeply saturated cognac tones (C6–C7) command premium value for collectors and connoisseurs.
