Almost all diamonds are "preowned". They routinely change hands so
many times it's often ridiculous. There are sources for Canadian
diamonds, and quite frankly I don't think they are any more
expensive than other diamond sources. There are many diamond sources
who sign off on a statement that their diamonds meet all the current
required protocols that guarantee against "conflict" diamonds. You
can easily locate many of them. If on the other hand, he is worried
about damage to the environment, no diamond is any less free of this
than any other. But, as I've said before, you should tell him that if
this is his issue he should first stop buying gasoline, using a
computer, etc. if that's a real worry for him. And if price is his
only issue, then he shouldn't be looking for a diamond with all of
these stipulations to begin with.
