The yellow kind of andradite known as topazolite would be an excellent gem-stone if only it were found large and transparent enough. |
The name topazolite is considered obsolete by many, with yellow andradite or yellow demantoid being preferred names for the stones described. |
Schists and serpentines yield the demantoid and topazolite varieties of andradite. |
The light colored andradite varieties topazolite and demantoid occur mainly in serpentinites and chlorite schists. |
The variety topazolite rarely occurs in crystals large enough to be worth faceting, and is thus rarely seen in jewelry. |
Most non-Russian stones are so yellow that they should perhaps be called topazolite, a greenish-yellow andradite. |
