High quality, natural octahedral diamonds are rare and are therefore very
costly. Pliny's comment is "The diamond, known for a long time only to
kings and then to very few of them, has a greater value than any other human
possession, and not merely than any other gemstone." From this, I assume
Romans did not generally wear diamonds because they could not afford them
and the idea that diamonds are cheaper than other stones because they lack
polish is false.
Diamond cutting increased the supply of available diamonds. European
diamond cutting appears to begin in Venice between 1330 and 1350. The
earliest representation of a facetting machine is by Zwolle in 1439. The
1456 date for Berquen is open to question as some sources list his birth as
1450. Berquen was the first cutter to grind off the upper and lower points
of the octahedral, the claim that he was the person who introduced diamond
cutting to Europe is false. Giacomo Tagliacarne is definitely contemporary
to Berquen and very likely predates him.
Since diamond cutting in Europe was 80-100 years old in 1434, I wouldn't
write off the claims that they were used then to ward off poison without
quite a bit more research.

Fine by me, but we might wish to take this off list since we are getting
away from cooking.
