Rhodolite

 

There is an intermediate group of garnets in the pyrope almandine series. It is a deep pink or pinkish-red color (known as rhododendron pink) and is called rhodolite, fnthe Greek rhodon, rose,' and lithos, “stone”. Rhodolite is a subvariety of pyrope-almandine characterized by its particular color.


Appearance The pinkish-red color is its main characteristic. The gems have good transparency and are almost always faceted, generally receiving a mixed, roughly oval or round cut. As always with transparent garnets, the luster is strong.


Distinctive features The color, luster and single refraction typical of garnets paint quite a clear picture. The stone is not, of course, pleochroic. The refractive index varies from 1.755 to 1 .765 and the density from 3.74 to 3 g/cm3-a very limited range. Rhodolite is distinguish from corundum of a similar color by its lack of pleochro and the fact that it does not fluoresce in bright light,
from rubellite by its lack of pleochroism, greater luster and absence of the marked birefringence of tourmaline, why is even visible with a lens. Its physical properties have to measured, however, to distinguish it from spinel.
