Gold has long been considered one of the most precious metals in the world. The main uses for gold are jewellery, dentistry, adornments on buildings and artistic expression. For thousands of years it has been used as an ornament of kings, a currency and standard for global currencies, and more recently, in a wide range of electronic devices and medical applications. I also use gold a inlay. Gold provides a distinct contrast against grey titanium. I use both 14k white and yellow gold.
