Rare Lazurite Gem in Quartzite Specimen

This is an extremely rare material called Lazurite, a gem-quality form of Lapis Lazuli. Lazurite, because of its colour and translucency, is often mistaken for the Royal variety of Blue Sapphire. There are three separate Lazurite crystals in this Quartzite rock specimen. Approx. 8cm x 6cm x 5cm. The largest Lazurite crystal is approx. 8mm diameter visible on the exterior of the Quartzite, its real size is unknown as the crystal is buried further beneath the Quartzite, however you can see a faint glow of blue suggesting its real diameter is approx. 11mm and also suggests it to have a perfectly hexagonal shape.
