Materials

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 purity standards

Too large of gauge for my lobe piercings

So bummed, I ordered the turquoise crystal stud to replace my lost fave turquoise stud that my double lobe was pierced with, but when it arrived it was wayyyy too high of a gauge for any of my lobe piercings. I also tried the Carina stud, which even though it says it’s a smaller gauge, it was also way too big. I spoke with customer service - they said the only options that would work are the Coastal and Pave Coastal hoops. 2 stars because it was pretty but really bummed.
