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.

As some reviewers have mentioned the flat back is a slightly larger gauge. I had no issues with that. For me this earring is great, I do with it was slightly shorter. Overall I really like the flat backs and will order more!

Doesn’t fit either piercing and too long

I was so excited for this style and bought two right away because I wanted to wear them in my lobe piercings and also a cartilage piercing. I’m super disappointed they don’t work for either!!! The bar is way too long for wearing in your regular lobe/the weight of the front of the earring pulls them for so they kind of hang and you can see the stud/bar. And that same stud/bar is bigger than a regular piercing hole so they won’t fit in my cartilage piercing either. I already threw away the packaging so didn’t try to return. So disappointed.


Absolutely love. They stay in, are beautiful and don’t bother my sensitive ears. Only complaint is they’re a little long. I wish they were more snug on my ears.
