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.

Tess Bilhartz
beautiful, but don't fit my piercing

Have been buying from tinilux for a while now and generally love the earrings. This earring, while beautiful, doesn't fit my piercing - the gauge is both too short and too thick. I spent about an hour trying to work it in and ultimately gave up.

Just Meh

I wanted to love this because my ears are so sensitive but I can’t even fit the earring through my piercing because the stud is so short. I am keeping a different pair of earrings that I got because I already wore them for a night but even those made my ears itch a little and the backs are EXTREMELY difficult to get on and off.

Love These!

This is the first pair in years that I have worn that hasn't made my ears freak out!!! I absolutely love these!!! I have been wearing these for weeks now with no issues!! My new favorite cartilage earring!!
Customer service was great as well! In my first order, the earring was stuck and broke when I tried to twist it apart; they were great and sent me a replacement. I haven't had any issues since!

I will say there was a learning curve on learning to put it in, though, but it does get easier over time!

Kelly Hill
Too large of gauge

I have not been able to successfully wear these since the gauge is too large for a normal piercing.

Also, I didn’t realize at the time of purchase this is only a single stud. It says it in the name, so that is more my own error.

Super cute earrings. Sadly my ears rejected them. So I can’t wear
