RUBY.
BALAIS RUBY.
This is a pale variety of the spinelle; it varies in color from light red to yellowish red. It probably derives its name from some supposed locality, or from some peculiar earth, in which it may have occurred.
The Balais possesses considerable beauty, and though not so rare as the spinelle, it is by no means common. It is much admired for its agreeable tinge of color, and, when pure and perfect, sells for a high price, but considerably less than the other distinguished stones of this class.
