    FAQs All About Cognac Diamond Jewellery

    What makes a cognac diamond unique?

    Cognac diamonds stand out due to their deep, amber-brown hues that exude warmth and richness. Unlike traditional white diamonds, cognac diamonds offer a more earthy and natural elegance. They’re completely natural and get their colour from trace elements during formation. Think of them as the fine wine of gemstones—mature, rich, and unforgettable. With their rising popularity, they’re not just a style choice but also a smart investment.

    Can a cognac diamond be worn daily?

    Absolutely! Cognac diamonds are just as durable as white diamonds, making them suitable for everyday wear. Whether set in a ring or a pendant, like this stunning necklace, they withstand the daily hustle with grace. To keep it gleaming, a quick clean with warm soapy water and a soft brush now and then does the trick. Just like your favourite leather boots or designer handbag, a little love goes a long way.

    Does this necklace come with a chain?

    Yes, it does! This cognac diamond necklace includes a matching 18kt gold chain, carefully chosen to complement the pendant’s design and provide a seamless, elegant look. You won’t need to search for the perfect match—it’s already part of the package. Just unbox, wear, and shine.

    What skin tones suit cognac diamonds?

    Cognac diamonds are incredibly flattering across a wide range of skin tones. Their warm undertones beautifully complement olive, tan, and deep complexions, and provide a striking contrast on fairer skin. The 18kt gold setting (especially in yellow or rose) enhances this effect, making the diamond glow against your skin.

    How do I style this necklace?

    Keep it simple or go all out! This necklace looks stunning as a standalone piece. For a layered look, match it with dainty chains of different lengths. Want to elevate the glam? Add matching diamond studs or a bold bracelet from our bracelets collection. The warm colour of the cognac diamond makes it easy to mix and match with other metals and stones too.

    Is this a good gift idea?

    Without a doubt. Whether for a birthday, anniversary, or “just because,” this cognac diamond necklace makes a memorable gift. It’s meaningful, elegant, and carries that bespoke, one-of-a-kind feel. Wrapped in our signature packaging and with the option to add a personal message, it’s ready to impress. And if you’re not sure, book a consultation and we’ll help you choose the perfect piece.
