This natural quartz cluster has nice crystalline formation with two bold, glassy clear terminations upon a sturdy, cloudy white matrix. Slight pyramidal black hematoid inclusions can be seen within these terminations along with a vivid rainbow (as photographed). This specimen is from the Lwena region of the Congo that produces fine citrine, and whilst this piece lacks the yellow colouration of that material, it has some of its form.

About Quartz

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. 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. Well-formed crystals deep within the Earth can reach colossal sizes, with some measuring several meters in length and weighing hundreds of kilograms.
