MATERIALS & CARE
Materials: Medical-grade (ASTM F-136) titanium with cubic zirconia crystals. Hypoallergenic and safe for sensitive skin.
Finish: Our jewelry is bonded with Titanium Nitride PVD. Titanium Nitride is a hypoallergenic material that is more durable and resistant to wear than traditional gold plating. PVD coating is also more environmentally friendly than traditional plating.
Care: Earring backings feature a silicone core for a comfortable, secure fit. To keep them performing at their best, avoid prolonged exposure to cosmetics and direct heat. Remove and clean your earrings weekly to prevent buildup from body oils and everyday wear. Waterproof and tarnish resistant. To maintain shine, polish with a soft cloth.

Frequently Asked Questions
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 ASTM F-136 titanium (aka medical-grade titanium), the same material doctors trust for medical implants. It's naturally hypoallergenic, nickel-free, and safe for the most sensitive of 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.
We take quality very seriously, and we craft our jewelry to last. We stand by our jewelry, and we offer a 365 Day Happiness Guarantee.

Perfect for my second piercing hole on both ears! Gave 4/5 stars because I have the single studs with the round backs that screw on as well and I do love that more. Overall love this brand and will continue to invest!

These earrings don’t bother my very sensible ears. I want to convert all my earrings to Maison Miru now! I love how dainty and sparkly they are. The backs are easy to put on and stay on well! :)
