Interesting Fact: Lapis Lazuli, or short Lapis, is not a mineral but a rock consisting mainly of Lazurite, to which it owes the blue colour, Calcite and Pyrite.
In the 1980ies the Swiss Gilson company produced a material which was marketed as "Synthetic Lapis" although actually it was an imitation, containing constituents not present in genuine Lapis. Physical properties like specific gravity and refractive index also differed from the real thing. Gilson's "Lapis" was available in different qualities, with and without Pyrite.
