    FAQs About Lab Diamond Engagement Rings

    Are lab diamond engagement rings real diamonds?

    Yes, absolutely! Lab diamonds are 100% real diamonds—chemically, physically, and optically identical to mined ones. They’re created in high-tech labs using the same conditions that form natural diamonds underground. So, while they’re man-made, they deliver the same brilliance, hardness (10 on the Mohs scale), and longevity. The only major difference? They’re far more sustainable and often more affordable, giving you greater size or quality for your budget.

    How are lab diamonds graded and certified?

    Just like natural diamonds, lab-grown diamonds are graded by reputable gem labs like IGI (International Gemological Institute) or GIA. They use the same 4Cs grading criteria: Cut, Colour, Clarity, and Carat Weight. For example, this ring features a 1.01ct lab diamond graded E colour and VVS2 clarity—a near-flawless stone with icy brilliance. Always look for certification to ensure quality and authenticity.

    Do lab diamond rings look different from natural ones?

    To the naked eye? No difference at all. Lab diamonds are virtually indistinguishable from natural diamonds unless examined with specialised lab equipment. The sparkle, clarity, and overall beauty are exactly the same. That makes lab diamond engagement rings a smart, stylish, and sustainable choice for couples who want maximum impact with minimal footprint.

    Are lab diamond rings cheaper than natural ones?

    Yes, generally they are. Lab-grown diamonds can cost 30–50% less than natural diamonds of the same size and quality. That means you can opt for a higher carat weight, better clarity, or simply save the difference for your honeymoon or future investments. More sparkle, same sentiment, better value.

    Can I customise a lab diamond engagement ring?

    Of course! At Ernesto Buono, we specialise in bespoke pieces. You can choose a different shape, setting, or even add accent stones to create something uniquely yours. Simply book an appointment and we’ll guide you through every step of the process. Whether you want vintage charm, modern minimalism or something totally unexpected, we’ll help you bring it to life.

    Why should I choose Ernesto Buono for my lab diamond ring?

    Because we combine ethics with elegance. Our lab diamond rings are crafted with the same care, precision, and design philosophy as our natural diamond range. Every gemstone is hand-selected and every piece is made with solid 18kt gold—no shortcuts. Plus, our personalised service means you get one-on-one support from start to finish. Choosing Ernesto Buono means choosing expert craftsmanship, ethical beauty, and timeless design in one unforgettable ring.
