24KT Gold PVD Titanium Internally Threaded with Heart Top. Manufactured from High Polish Implant Grade Titanium (Ti-6AL-4V-ELI ASTM F136)
 
The gold color, once deposited, stays bonded to the titanium, and does not flake or wear off. Gold PVD is not the same as gold plating, though the two are often confused, as it is more durable and long-lasting. It has a high resistance to daily wear and tear, and is an attractive, more affordable option to solid gold jewelry. 24kt gold is the purest form of gold.  More information is available in the FAQ section.
