Implant grade titanium is both hypoallergenic and bio-compatible. Bio-compatible titanium resists wear and tear from bodily fluids. As a result, titanium is popular for use in medical implants. Due to its porosity, polished titanium is key for body jewelry. Our titanium jewelry uses a mirror polish. the gold or rose gold PVD can irritate if you have metal sensitivities. The colour tone options are PVD titanium over G23 titanium- This stands for Physical Vapour Deposition. PVD is more durable and therefore lasts longer than traditional plating. However, the plating may irritate allergies. Blackline is a titanium carbide PVD coating. Titanium carbide is deposited onto the metal as a vapour. As a result, the metal looks black, and does not affect the hypoallergenic status of the titanium. The top has internal threading. This means it screws into the foot.
