The term 'were' purports to look back into the history of diamonds as adornment, which history reaches back about 6,000 years.
Copper is a relatively soft metal and would not be secure for a diamond -- for long. There may have been diamonds that were set in copper.

I would say 98% of the time if it is gold plated it is not a real diamond. diamonds are mounted in silver but not very often and they are lower quality.
Sure. In the past people would not see diamonds set in silver or turquoise in gold. Now you see both, though not very common. Turquoise has been found in silver in the South West, thus associated with silver. Sterling Silver is a bit soft for setting diamonds, thus the setting either has to have some gold in it, or copper or be very heavy ( the prongs) of something to make up for the softness of the sterling. Thus the exact same style that you see done in gold could not be done in sterling . That does not exclude the combination though
