Unlike the way better known white and rose golds of the jewelry world, the black gold of the industrial world (which sounds so much more poetic than “crude oil”) and like its true counterpart purple gold, blue gold is a mixture of gold and indium that results in a bluish concoction that looks nothing like the color or texture of either of its constituents. In fact, it closely approximates crystalline osmium though, of course, much less dense. It's perfect for those who appreciate the beauty of crystals and gold element specimens. Use the included jeweler's loupe to examine the intricate details up close and marvel at the stunning blue hue. Add this rare bullion to your collection today.
