And it maketh a
man more strong and more sad against his enemies. And it healeth
him that is lunatic, and them that the fiend pursueth or
travaileth. And if venom or poison be brought in presence of the
diamond, anon it beginneth to wax moist and for to sweat.
There be also diamonds in Ind that be clept violastres, (for their
colour is like violet, or more brown than the violets), that be
full hard and full precious. But yet some men love not them so
well as the other; but, in sooth, to me, I would love them as much
as the other, for I have seen them assayed.
Also there is another manner of diamonds that be as white as
crystal, but they be a little more trouble. And they be good and
of great virtue, and all they be square and pointed of their own
kind. And some be six squared, some four squared, and some three
as nature shapeth them. And therefore when great lords and knights
go to seek worship in arms, they bear gladly the diamond upon them.
I shall speak a little more of the diamonds, although I tarry my
matter for a time, to the end, that they that know them not, be not
deceived by gabbers that go by the country, that sell them.
