    FAQs: Large Lab Diamond Stud Earrings

    Are lab diamonds real diamonds?

    Yes. Lab diamonds are chemically identical to mined diamonds. These IGI-certified D/VS1 stones offer the same brilliance, fire, and durability—just without the environmental cost. You get real diamonds, responsibly made.

    Are these suitable for everyday wear?

    Absolutely. Though they’re bold, the six-prong setting and screw-back posts make them secure and wearable daily. Perfect for dressing up jeans or adding polish to a power suit.

    What is the total carat weight?

    These earrings feature two round brilliant lab diamonds totalling 3.22ct—so about 1.61ct per ear. It’s a showstopper size that still feels refined, not over-the-top.

    Do they come with certification?

    Yes, both diamonds are IGI-certified, with details on carat, cut, colour (D), and clarity (VS1). You’ll receive these documents with your purchase, ensuring authenticity and value.

    Are they a good investment gift?

    Definitely. These earrings are perfect for milestone celebrations—weddings, anniversaries, promotions, or birthdays. Their timeless design ensures they’ll never go out of style, and their lab-grown origin adds meaning to the beauty.

    Can I see them in-store before I buy?

    Yes! Book an appointment to try them on at our Sydney boutique. You’ll see the diamonds in natural light and get personal styling guidance from our expert team.
