Out of interest, I probably have the largest DIAMONIQUE stone ever made.
It is about the size of a hand-palm, and is 1000's of carats (can't remember exactly).
QVC had a few made to demonstrate Diamonique, and eventually sold them off.
It came in a polished wooden box with a glass lid so you could see the "diamond" inside.
It is a superb object to look at and handle, but that is all you can do with it.
Still, I'm glad I bought it when it was available.
