What's behind this brass box: the Unicorn's favorite crystal? This is a group of natural crystals from Brazil with Titanium plating! The process is similar to gold plating. A thin layer, of the order of a micron, of gold and titanium, merge on the surface of the quartz, in an autoclave oven. The result is a permanent glow of purple colors.
