Materials & Care
We only use metals your ears will love. Every pair of Sunday Moon earrings is made from either 925 sterling silver or Implant Grade ASTM F-136 Titanium.
Both are hypoallergenic, comfy and perfect for sensitive ears. Think of them as the “no drama” metals: durable, lightweight, and ready for everyday stacking.
🌙 925 Sterling Silver — What You Need to Know
Our 925 sterling silver pieces are crafted from 92.5% pure silver, giving them their beautiful shine and lasting quality. To keep them looking luminous for many moons, we add a special anti‑tarnish layer that helps protect against oxidation and prolongs the life of your earrings.
Sterling silver is naturally hypoallergenic, comfortable and perfect for everyday wear — but like all real silver, it can gently darken over time when exposed to air, water or the products we use day‑to‑day. Our protective coating slows this process right down, helping your jewellery stay brighter for longer.
With a little care, your silver will stay glowing season after season.
✨ How to Care for Your Sterling Silver
Wear it often
Silver actually stays brighter the more you wear it — your natural skin oils help keep it polished.
Polish regularly
Use a soft cloth or silver‑cleaning cloth to gently buff away any dullness and keep your pieces glowing.
Keep it dry when you can
Water won’t damage sterling silver, but it can speed up oxidation (darkening), especially when mixed with:
-
Shampoo & conditioner
-
Chlorine
-
Perfume & body sprays
-
Skincare products
Removing your jewellery before showering, swimming or working out will help it stay bright for longer.
Clean gently if tarnish appears
A little mild soap + warm water works wonders. Rinse well and dry thoroughly with a soft cloth.
Store it safely
Keep your jewellery in your tarnish‑free Sunday Moon box or an airtight pouch to protect it from moisture and the elements.
✨ ASTM F136 Titanium
Our titanium pieces are crafted from implant‑grade ASTM F136 titanium — one of the safest, most skin‑friendly metals you can wear. It’s ultra‑light, hypoallergenic and wonderfully gentle, making it perfect for sensitive ears and new piercings.
This grade of titanium contains only trace amounts of nickel (typically less than 0.05%), which is why it’s considered safe for almost everyone with sensitivities. It helps piercings stay calm, comfortable and irritation‑free.
To give our titanium styles their beautiful golden finish, we use a premium PVD coating. Unlike traditional plating, PVD is incredibly durable, long‑lasting and resistant to wear — meaning your earrings stay luminous for many moons.
And the best part? Titanium with PVD coating is waterproof, sweat‑proof and designed for 24/7 wear. You can shower, swim, sleep and live in your earrings without worrying about discolouration.
In short: Strong, lightweight, hypoallergenic, waterproof and made for everyday (and every‑night) comfort.
