 SECT. II. Chrysoberyl or Oriental Chrysolite, and Cymophane

chrysoberyl, though differing in some characters from the sapphire, yet closely approximates to it in hardness and specific gravity. When pure, it is of a gold yellow color inter-mixed with green, exhibiting a peculiar richness of tint, and in lustre yields only to the brilliant.

occurs in Brazil, in the alluvial soil, associating with diamonds, usually in grains or rounded pieces, and sometimes in crystals: a stone of twenty carats is rarely met with.
