is related that a French glass maker, happening to let some brass
filings fall into his glass-pot, was surprised to find that the
product presented a beautifully-spangled appearance. To this
gold-spotted glass the name of Avanturine was given, because it had thus been formed par aventure—"by
accident." The name was afterwards applied to a mineral which presents
an appearance somewhat like that of the avanturine glass
This
mineral, though rare, is nothing more than a translucent variety of
Quartz, generally of brownish-red but sometimes of green colour, and
having disseminated throughout its mass a vast number of glittering
points which appear generally to be minute scales of Mica. It is used
to a limited extent as an ornamental stone.
