Gold has been used as a symbol for purity, worth, royalty, and notably roles that mix these properties. Gold as a sign of wealth and prestige was ridiculed by Thomas More in his treatise Utopia. On that imaginary island, gold is so plentiful that it’s used to make chains for slaves, tableware, and lavatory seats. When ambassadors from other international locations arrive, dressed in ostentatious gold jewels and badges, the Utopians mistake them for menial servants, paying homage instead to the most modestly dressed of their celebration. The first recognized cash containing gold had been struck in Lydia, Asia Minor, around 600 BC.
Palladium-gold alloys are costlier than these utilizing nickel. High-karat white gold alloys are more proof against corrosion than are both pure silver or sterling silver. The Japanese craft of Mokume-gane exploits the colour contrasts between laminated coloured gold alloys to provide decorative wood-grain results.
