Sentences with PHENACITE (4)
The degree of symmetry is the same as in the mineral phenacite, there being only an axis of triad symmetry and a centre of symmetry.
This lower degree of symmetry, which is the same as that of dioptase and phenacite, is occasionally shown by the presence of an obliquely placed rhombohedron, and also by the want of symmetry in the etching and elasticity figures on the faces of the primitive rhombohedron.
Such a simple test may, for example, be applied for distinguishing certain faceted gem-stones: thus zircon and phenacite are optically positive, whilst corundum (ruby and sapphire) and beryl (emerald) are optically negative.
The following list gives the number of rings for each mineral species: Corundum 12 Spinel 17 Chrysoberyl 8 Quartz (amethyst, tiger-eye, chrysoprase) 3 Peridot 1 Spodumene 1 Labradorite 1 Beryl 4 Andalusite 1 Tourmaline 20 Opal (precious, fire, black and milk) 10 Zircon 45 Phenacite 5 Enstalite 1 Moonstone 2 Garnet 19 Topaz 8 Cordierite 2 Sphene 1 Turquoise 1 Only three of the rings are set with more than a single stone.
