I'm not entirely sure what your colleagues were referring to as a "piece diamond." It could be a term specific to their industry or region. However, if they were talking about diamonds and large sums of money, it's likely that they were discussing real diamonds, rather than fakes. Diamonds are highly valued for their beauty and rarity, and can command high prices depending on their size, quality, and other factors. It's possible that the term "piece diamond" refers to a diamond that has been cut into a specific shape or size, but without more context it's hard to say for sure. And maybe they also meant lab-grown diamonds (
