I'm not sure what wealthy person would even want to drink out of a golden coffee cup studded with diamonds (Donald Trump maybe?) but one exists nevertheless, thanks to German porcelain maker KGM. The cup and saucer set has a base of fine porcelain that's accented with 24 karat gold, blue cobalt, and diamonds. Valued at €30,000 the design looks a little dated and gaudy to me, but I suppose as a collector's item or investment piece it's interesting enough -- certainly a conversation piece!
