Locality - Brandberg Area, Dâures, Erongo Region, Namibia Size – 48 x 32 x 27mm Weight – 52g
This natural specimen features an attractive double terminated zoned amethyst crystal with clear tips and a frosty white centre. Despite a significant fracture to the crystal (as seen in the 10th photo), it is still an excellent piece. Quartz specimens from the Brandberg Area in Namibia are regarded as some of the finest in the world and are highly sought after by discerning mineral collectors.
Quartz is the most common mineral found on the surface of the Earth, occurring in virtually every locality. Pure crystals are colourless, transparent and hard, though many are coloured by natural processes such as irradiation or by the presence of certain elements within them. These coloured varieties include the popular gemstones amethyst, purple quartz, and citrine, yellow quartz. Some quartz crystals have unique inclusions of minerals that have grown within them, such as golden rutile, tourmaline or chlorite, and others may show silvery reflective internal veils and bright rainbows. Whilst the majority of quartz is created from molten magma that has cooled and crystallized, much quartz also chemically precipitates from hot hydrothermal veins.
