    Lab Diamond Necklace – FAQs

    Is a lab diamond a real diamond?

    Yes, lab diamonds are chemically and visually identical to mined diamonds. This 1.60ct lab-grown stone is IGI-certified and offers the same fire, brilliance, and durability—just created in a more ethical and sustainable way.

    Does the necklace come with a chain?

    Yes! Unlike some pendants, this necklace comes complete with a finely crafted 18kt white gold chain. It’s designed to sit perfectly and securely, ready to wear straight out of the box.

    Can I wear this necklace every day?

    Definitely. The secure prong setting and solid white gold chain make it a practical option for everyday wear. It’s lightweight, comfortable, and pairs with any outfit—from office wear to evening dresses.

    How should I care for this lab diamond necklace?

    Clean it with warm water, mild soap, and a soft brush. Avoid contact with chemicals and perfumes. When not in use, store it in a soft pouch or separate compartment to prevent scratching. Bring it in for a yearly professional polish—we’re happy to help.

    What makes this a good gift?

    It’s timeless, ethically made, and comes with a wow factor thanks to the high-grade diamond and gold chain. Perfect for birthdays, anniversaries, bridal gifts, or milestone achievements—this necklace is a heartfelt, high-impact choice.

    Can I see this necklace in-store before purchasing?

    Yes. We offer personalised viewings at our Sydney boutique. Book your appointment here to see the diamond up close and experience its sparkle in natural light.
