Trust Badge


ASTM F-67: Pure, unalloyed titanium. This is the safest metal for sensitive ears because it is the least likely to cause a reaction. We use this for almost all of our earrings.

ASTM F-136: Implant grade titanium. This is an biocompatible alloy containing aluminum, vanadium, and titanium. We use this for our flat back studs.

STAINLESS STEEL: We use this as a base metal for our bracelets and necklaces. We always use nickel free and lead free stainless steel. It is then plated with titanium nitride, a biocompatible material, to further protect sensitive skin.

COATING: Titanium nitride PVD is applied to our gold jewelry to give it an 18k gold color. Titanium nitride is a hypoallergenic material that is more durable and resistant to wear than gold plating.

CARE: Since the materials we use are non-tarnishing, our jewelry can be worn in the water and will not change color, rust, tarnish or turn green. 

Tested for Purity

We lab test our earrings to ensure they meet our Clean Jewelry standards

Earring back too tiny, lost and no response to order new one

The day I received the earring and tried to put it on, I dropped the back down the sink. My fault for trying it over a sink - but the back is SO small it’s hard to hold it and twist it on. I immediately reached out to customer service to ask about buying a new one (the back only) with still no response. I’ve contacted them twice. So disappointing because for one earring it is not cheap. I can’t wear it with no back and I’m not ordering another one.
