Alchemists of the medieval age strived to turn cheap metals into gold with no avail. Chemists of today have already achieved turning metal into gold, however it’s not something that one could make profit on. 30 years ago bismuth was successfully transmuted into gold by chemists. The bismuth was collided at near light speeds by beams of carbon and neon nuclei. It required a lot of energy and the result was a miniscule amount of gold.
