    Lab Diamond Necklace – FAQs

    What is a lab diamond, and how is it different from a mined diamond?

    Lab diamonds are real diamonds—identical in chemical, physical, and optical properties to mined ones. The only difference is how they’re created. Lab diamonds are formed in controlled environments using cutting-edge technology, offering the same sparkle, clarity, and strength—without the ethical and environmental concerns of traditional mining.

    Is this necklace suitable for everyday wear?

    Absolutely. The minimalist design and secure setting make it ideal for daily use. Whether you’re heading to a meeting or out to dinner, it fits in perfectly. Just remember to remove it during high-impact activities like sports or heavy cleaning to keep it looking flawless.

    Does this necklace come with a chain?

    Yes, it does! This lab diamond necklace includes the chain, so you’re receiving a complete piece—ready to wear straight out of the box. No need to buy a separate chain or worry about matching metals or lengths—it’s already perfectly styled for you.

    Is it a good gift option?

    It’s an excellent choice. This necklace is a timeless, elegant gift that suits any occasion—birthdays, anniversaries, milestones, or even “just because.” The lab diamond adds meaning and modern values to the luxury, making it a thoughtful piece anyone would love to receive.

    How do I clean and care for it?

    Use mild dish soap and warm water with a soft toothbrush to gently clean it. Rinse, pat dry, and store in a soft-lined jewellery box. Avoid contact with harsh chemicals or abrasive surfaces. Bring it in for a professional clean and check-up once a year to keep it in perfect condition.

    Can I try this necklace on before purchasing?

    Yes, definitely. You can book a private appointment at our Sydney boutique to see the necklace in person, try it on, and explore pairing options. Our team is here to help you find a look that’s totally you.
