Crystal Trinity Threaded Flat Back Earring

Absolutely. Our jewelry is intentionally crafted for real life — from morning workouts to your evening wind-down. Our pieces are made to be worn continuously, so you can shower, sleep, exercise, and go about your day without taking your jewelry on and off.

Yes, our jewelry is intentionally made to be safe for sensitive skin. We take skin sensitivities very seriously, so we craft our jewelry in medical-grade (ASTM F-136) titanium, the same material doctors trust for medical implants. It's naturally hypoallergenic and nickel-free. Read our guide to the best earrings for sensitive ears.

PVD (Physical Vapor Deposition) is a modern plating process that creates a finish that's more durable than traditional gold plating. The result is jewelry that better withstands the rhythms of everyday life, helping its color stay beautiful through regular wear.

Absolutely — you don't have to take off your jewelry when you're working out or showering. Our titanium jewelry is waterproof, sweatproof, and made to keep up with your daily life. You can wear it all day and night, through workouts, showers, and the occasional nap. Or as we like to say, sweat, shower, sleep, repeat.

Titanium is remarkably strong for its weight, making it both durable and almost weightless. That means you can wear bold, sculptural earrings that feel surprisingly comfortable — often so comfortable you'll forget you're wearing them.

Most people wear our standard (6mm) backing comfortably. If your ears are thinner, or you find that your earrings are drooping, you may prefer a short (4mm) backing. If your piercings are newer or you have a fuller lobe, a long (8mm) backing may be a better fit. If you're unsure, just message our Customer Care team at hello@maisonmiru.com. We're always happy to help you find the right size.

Nap Earrings® use a secure push pin flat back instead of a traditional butterfly backing. The flat back sits comfortably against your ear, while the pin gently bends to create a secure fit that stays in place through sleep, showers, and everyday wear. How to Insert Your Nap Earrings®.
