PVD stands for Physical Vapour Deposition. In other words, the titanium carbide deposits onto the metal as a vapour. As a result, the titanium looks black. This coating is hypoallergenic. The yellow gold and rose gold tones are PVD. PVD is more durable and therefore lasts longer than traditional plating. If you have sensitivities, we recommend wearing our steel, anodized, blackline, or untreated titanium options instead. Show us where you wear yours with #BodyModsFamous on Instagram.
