It is the same in the U.S., I think. According to the FTC, it must be disclosed if it is grown in a lab.
So, I guess a natural diamond can JUST be called a diamond, but a lab diamond must ALWAYS be called a lab diamond or something similar. I could argue when you say just the word "diamond" you mean "natural diamond." It does not need a qualifier.
