Up until 1950 mercury was used by gold miners to absorb gold from crushed gold ore. This process was called amalgamation. To recover gold back from mercury all you had to do is evaporate it . Since it was extremely polluting and inefficient it was stopped to be used in favour of new technologies like floatation and others. Man made diamonds or as they are called industrial diamonds are easily recognisable and for that reason not used in jewellery. It is bad example. One carat of industrial grade in bulk may cost bellow a dollar. Jewellery grade runs $100 to $10,000. Market for some semi-precious stones has been undermined by man laboratory grown staff. This is only true with crystal based stones that can be grown in lab.
