ZIRCON.

SECT. X.

Zircon—Hyacinth and Jargoon.

The Hyacinth is of an orange red color, and, when free from defects, is a beautiful and brilliant stone. Small specimens are common in Ceylon, where they are cut and polished; they rarely exceed the size of a bean, but they have occurred large enough for brooch stones. As they are generally full of flaws, they are not often employed in jewellery.

THE JARGOON.

Though differing in color, is of the same class with the preceding. It is a transparent stone, greatly resembling colored crystal, but when polished, it has considerably more lustre.
