    Radiant cuts are loved for their sharp corners, clean lines and brilliant sparkle – and when they’re lab grown, you get all the dazzle without the environmental impact. These E colour, VS2 clarity diamonds are carefully matched for symmetry and brilliance, then hand-set in solid yellow gold for a warm, eye-catching contrast. The secure screw-back setting ensures comfort and confidence all day long.

    FAQs – Radiant Cut Lab Diamond Earrings

    What makes radiant cut lab diamond studs special?

    Radiant cut diamonds combine the elegance of emerald shapes with the brilliance of round cuts, giving you the best of both worlds. Their trimmed corners and multiple facets offer exceptional sparkle. When set in 18K yellow gold, they become even more striking. Plus, using lab diamonds ensures you’re investing in ethically sourced beauty.

    Are lab diamonds real diamonds?

    Absolutely! Lab diamonds are real diamonds with the same physical, optical, and chemical structure as mined ones. They’re graded the same way and deliver the same fire, brilliance, and hardness. Therefore, you get luxury and sparkle without the environmental impact.

    Can I wear these studs every day?

    Yes! These earrings are perfect for daily wear. Their screw-back design offers added security, and the 18K gold setting is hypoallergenic and durable. However, we recommend removing them before swimming or showering to preserve their lustre.

    How do I clean and care for my lab diamond earrings?

    Simply soak the studs in warm soapy water, then gently clean them with a soft toothbrush. Rinse well and dry with a microfibre cloth. Additionally, store them in a soft pouch when not in use to prevent scratching.

    Can I customise the metal or diamond size?

    Yes, at Ernesto Buono, we offer custom options for all our fine jewellery. You can select from yellow, white, or rose gold, and choose your preferred carat weight or diamond shape. To create your ideal pair, book an appointment.

    Why choose Ernesto Buono for lab diamond earrings?

    We blend Italian craftsmanship with modern ethical values. Our earrings are made with high-quality lab diamonds and solid 18K gold, ensuring durability and timeless appeal. Whether you’re purchasing your first fine jewellery piece or expanding your collection, we offer a premium experience from design to delivery.
