PRECIOUS STONES.
Emerald has been found in the Salzburg Alps at Sedlalp, with Tourmaline and Iron Pyrites in mica-schist. In the Mourne Mountains in Ireland Beryl is found with Quartz, Felspar and Topaz, in druses in the granite.
In Australia, in New South Wales, at Emmaville, Emerald occurs in pegmatite with unusual associates, as
Cassiterite, Mispickel and Fluor Spar, and the more usual associate Topaz.
Fine varieties of Beryl are sometimes brilliant cut, the deeper coloured specimens requiring a rather shallow form, while the paler shades must be given a good depth to ensure a fine colour effect. More often a mixed cut is used, or a pure-step cut. Good stones with fine colour may be mounted à jour, but stones of poorer colour are often improved by being mounted with foil in a closed setting.
