FAQs – Lab Diamond Tennis Bracelet (3ct): Everything You Should Know

What makes this 3ct lab diamond bracelet unique?

It’s a bold, elegant statement made with heart. Featuring 74 F/VS lab-grown diamonds, it offers the same beauty and brilliance as mined diamonds—yet with none of the ethical concerns. Plus, the 18kt white gold setting adds refinement and durability, making it a smart, timeless investment in your style.

Are lab diamonds real?

Yes. Lab diamonds are chemically and visually identical to natural diamonds. They’re created using high-tech processes that replicate the way diamonds form in nature—giving you all the sparkle and strength without the environmental toll. And often, they offer better value for carat weight and clarity.

Is this bracelet durable enough for everyday wear?

Absolutely. Lab diamonds are just as hard as natural diamonds (10 on the Mohs scale), which makes this bracelet ideal for daily wear. The secure box clasp with a safety latch ensures it stays in place, whether you’re heading to work or out for dinner. A quick professional clean every so often will keep it shining like new.

Is this bracelet a good gift idea?

Yes—it’s a beautiful, thoughtful gift. Whether for a birthday, anniversary, graduation or just because, this bracelet says “you’re worth it” in every way. It arrives in our signature Ernesto Buono packaging and suits a range of personal styles—from minimalist to statement.

Can I customise this bracelet?

Absolutely. You can personalise everything from the total carat weight and length to the metal colour—choose between white, yellow, or rose gold. We can also tailor the diamond clarity or even offer a custom clasp. Just book a consultation with our expert jewellers to create your perfect version.

Can I style it with other pieces?

Definitely. This bracelet looks stunning solo but also layers beautifully with bangles, cuffs, or other tennis bracelets. You can also pair it with our Tennis Necklaces or Lab Diamond Earrings for a cohesive, elevated look.
