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.
Today, a buyer can commission that a diamond be set in rose gold, which is gold mixed with copper, to give the setting somewhat the copper colour, while securing the gem in a stronger metal.
Real diamonds are typically set in precious metals like gold or platinum due to their durability and value. Copper and sterling silver are not commonly used for setting diamonds, as they are softer metals that may not provide the necessary support and security for the stone.
Yes, it is common for real diamonds to be set in gold plated settings. This can allow for a more affordable option while still maintaining the look of a gold setting for the diamond. However, the plating may wear off over time and need to be redone.
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
Yes, some diamonds will give this appearance.
no there was never a copper quarter
There is no evidence that any American country has ever 'fought' over diamonds.
It would be possible if it ever happen.
The setting of the book After Ever After by Jordan Sonnenblick is in New Jersey.
You can earn diamonds by finishing certain quests. The reward on these quests are diamonds. Or of course by buying them in the store. (I don't recommend that. It's not worth it. You can go on the game without ever using diamonds.)

Every hardware store I've ever been in keeps copper fittings.
