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.

So cute!

These are great—wanted something really high quality as the first earring to wear in my new second lobe piercings. The little stars are adorable.

Alison Scheid
Beautiful and Simple

This was the first pair of titanium earrings that I purchased and I just love these! They design is so cute and they are simple for everyday wear. My sensitive ears have never felt so great!

Your Ears' New Best Friend!

Your ears will thank you! If you have had problems with earrings in the past, look no further. This will be one of the best investments you will make!

Meghan Reilly
It’s not hopeless!

I haven’t been able to wear standard earrings for years, even ones touted to be “hypoallergenic” or nickel-free. I thought it was a lost cause. I got these titanium studs on a whim and after a few wears I can safely say I can wear earrings again!
