A flat-back stud is the earring you never take out: a lab-grown diamond set in solid recycled gold, secured with a smooth flat back that sits flush and comfortable against the lobe — no poking, no catching, even when you sleep. They're the anchor of a curated ear, worn solo in a first or second piercing or stacked across the lobe and helix. Put them in once and forget they're there.

Can I sleep in flat-back studs?

Yes — lab-grown diamonds are chemically and optically identical to mined, with the same fire and hardness, just a cleaner origin and more carat for your budget.

Are the diamonds lab-grown?

Yes — lab-grown diamonds are chemically and optically identical to mined, with the same fire and hardness, just a cleaner origin and more carat for your budget.

Are they good for a new piercing?

Their flat, comfortable backs make them a popular choice for healed piercings; check with your piercer for fresh ones.

Are they solid gold?

Solid recycled gold, never plated — so it holds its colour, won't tarnish, and can be worn every day, shower and sleep included.
