Material
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.
