    FAQs: Lab Diamond Necklace

    Is the chain included with the necklace?

    Yes—this piece comes with the 18kt yellow gold chain included. It’s a fixed design, made to sit just right on the collarbone. No need to purchase anything extra—it’s ready to wear straight out of the box.

    Are lab diamonds real diamonds?

    Absolutely. Lab diamonds are chemically, optically, and physically identical to mined diamonds. They offer the same brilliance and hardness but are made in a lab using advanced technology. This means they’re more ethical and environmentally friendly—no compromise on quality or sparkle.

    Can I wear this necklace every day?

    Yes, it’s designed for daily wear. The diamond is securely set, and the solid 18kt gold chain ensures durability. Whether it’s for the office, dinner dates, or running errands—it’s your everyday luxury, made effortless.

    Is this necklace a good gift?

    It’s a brilliant gift choice. Timeless, elegant, and made to last—ideal for birthdays, anniversaries, weddings, or just because. The included chain makes it an easy, complete gift that won’t require any extra effort from the recipient.

    How do I clean and care for it?

    Use a soft toothbrush with warm water and gentle soap to clean. Pat dry with a lint-free cloth. Avoid harsh chemicals and store it separately to prevent scratches. For a professional polish, bring it into our Sydney store anytime.

    Can I see it in-store before buying?

    Definitely. Book your private appointment at our Sydney boutique to try this necklace on and explore pairing options. Our experts will guide you through the collection and help you find your perfect piece.
