LESSON XII

COLOR—Continued

GREEN STONES

Let us first consider what mineral species are most likely to give us green stones. Omitting the semi-precious opaque or translucent stones we have:

1. Grass-green beryl (the emerald) which is, of course, first in value among the green stones and first in the fine quality of its color.

2. Tourmaline (some specimens of which perhaps more nearly approach the emerald than any other green stones).

3. The demantoid garnet (sometimes called "olivine" in the trade).

4. True olivine (the peridot and the chrysolite of the trade).

5. Bluish-green beryl (aquamarine).
