Champagne diamonds, also known as brown diamonds, are a captivating variation of the diamond gemstone that display a unique and warm colour palette reminiscent of champagne or cognac. Unlike traditional colourless diamonds, champagne diamonds possess a range of shades from light champagne to rich cognac and even deep chocolate brown, giving them a distinct and enchanting appearance.
The colour of champagne diamonds is caused by the presence of nitrogen impurities within the crystal structure. These impurities absorb certain wavelengths of light, resulting in the captivating earth-toned hues that characterize these diamonds. The intensity of the colour can vary, and some champagne diamonds may exhibit secondary colours such as yellow, orange, or even hints of pink.
