So, one should rather go with comments from people like "Peter W.

Thanks. But better, educate yourself. Take courses in gemology, or do your
reading NOT in the old traditional books, which are out of date and often
incorrect. Rather, do your reading in current, up to date, respected books on
gemology and gem testing.

I am researching old methods to study how people actually arrived at
the current ones in stages. Who knows what could be hidden out there,
I could land up with some methods which could rather bring down the
overall production cost. Again, what Peter is trying to point out is
right, some times it can be real dangerous trying things. So, readers
please use your own minds, be real careful.... Diamonds are very very
precious.
