CHAPTER VII.
AVANTURINE.
Τ 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.
