Why can't we make diamonds in a lab??

Isn’t the Russian Mafia the main producer of fake diamonds ??? Doesn’t sound too PC to me…

:confused:

So bascially - the Russian diamonds are just as sparkly and clear - if not more so - than natural diamonds? And presumably vastly less expensive?

Is there no major advantage to natural diamonds over high grade manufactured ones other than the sentimental aspect?

If so, where can I buy the manufactured ones?
