    FAQs – Lab Diamond Tennis Bracelets

    What are the benefits of choosing lab diamonds for a tennis bracelet?

    Lab diamonds offer all the beauty and durability of natural diamonds but are created in a sustainable, ethical way. Therefore, they’re a smart choice for those who value conscious luxury. Plus, they tend to be more affordable, allowing for larger carat weights at accessible prices.

    Can I wear a lab diamond tennis bracelet every day?

    Yes! These bracelets are designed for daily wear. Moreover, the 18K white gold setting and secure clasp provide both strength and comfort. However, we recommend removing it during intense physical activities or when using harsh chemicals to maintain its pristine condition.

    Are lab grown diamonds really identical to natural diamonds?

    Absolutely. Lab grown diamonds have the same physical, chemical, and optical properties as natural diamonds. They’re graded the same way by gemological institutes and are indistinguishable to the naked eye-in fact, even experts require specialised tools to tell them apart.

    Can this bracelet be customised?

    Yes, it can. At Ernesto Buono, we offer full customisation options-from total carat weight to bracelet length and metal tone (white, yellow, or rose gold). To create your perfect piece, book an appointment and speak to our experts.

    What makes Ernesto Buono’s bracelets different?

    Our bracelets combine traditional Italian craftsmanship with modern ethical values. Not only are they made with 18K gold, but we also hand-select each diamond (lab or natural) for exceptional quality. Our designs are timeless yet trend-aware-so you’ll love your bracelet now and for years to come.

    How do I clean and care for a lab diamond bracelet?

    Clean it regularly with warm soapy water and a soft toothbrush. Rinse thoroughly and dry with a lint-free cloth. Additionally, store it in a soft pouch or jewellery box to avoid scratching. For long-term care, bring it in for professional cleaning and inspection once a year.
