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 Clean Jewelry standards

Customer Reviews
No sensitivity issues at all, even after wearing for 24 hours straight. I'm happy I took a chance on ordering these, as so many online products don't live up to the hype. Definitely would recommend to anyone who gets red, bumpy, crusty ears after wearing cheap or so called 'hypo allergenic' earrings.
I really love these star earrings. I chose the silver pair. They are well made and pair well with other earrings because they are not too big. I can also sleep with them in and feel no discomfort due to a long post as with some other earrings. I would highly recommend these to others. They are very cute.
My daughter who's 9 has had nothing but trouble with her newly pierced ears. After having them repierced, buying stainless steel studs to replace the 2nd piercing after 6 months she was still having issues. I came across these while looking for another options for sensitive ears. They came quickly and not only does she love the little stars, her piercings have never been better! Huge thank you, definitely will be buying more.
These are the first earrings I’ve had that I can leave in for longer than a few hours without irritation! Thank you!
The Castor Studs were a gift for my great niece. They have solved the problems she was having with other pierced earrings, and they look great. Will be buying more for future gifts.
