    FAQs: Two-Tone Diamond Necklace in 18kt Gold

    Can I wear this diamond necklace every day?

    Absolutely. This necklace is crafted in solid 18kt gold and fitted with bezel-set diamonds—both durable choices for daily wear. The design is sleek and snag-free, and the 22.8g weight ensures it sits comfortably and securely. Just remove it before swimming or gym workouts to maintain its shine over time.

    What does two-tone gold mean?

    Two-tone gold combines two gold colours—in this case, yellow and white gold. This necklace beautifully alternates the tones to enhance the flow of the design while offering styling versatility. It pairs just as easily with silver jewellery as it does with yellow gold, making it a go-to piece for layered looks.

    Are the diamonds in this necklace natural?

    Yes, the 11 diamonds in this necklace are 100% natural and ethically sourced. We use round brilliant-cut stones for maximum sparkle, and each one is bezel-set for added security and smooth styling.

    What can I pair this necklace with?

    This necklace is highly versatile. It looks amazing layered with shorter chains or worn solo for a clean, sculptural look. You can also pair it with our diamond studs, tennis bracelets, or a yellow gold cocktail ring to amplify the glamour.

    Is the necklace adjustable?

    This necklace is designed at a fixed length to maintain its balanced link pattern and sit perfectly along the neckline. If you’d like to explore custom length options or extensions, our team would be happy to assist during your appointment.

    What makes this necklace a good investment?

    Between the solid 18kt gold weight (22.8 grams), natural diamonds, and timeless design, this necklace holds both sentimental and intrinsic value. It’s a wearable heirloom that won’t go out of style. Investing in fine jewellery from Ernesto Buono means choosing lasting quality, craftsmanship, and elegant design in one perfect piece.
