Large Madagascan Clear Quartz Freeform - 91mm, 150g
Locality - Madagascar Size – 91 x 36 x 31mm Weight – 150g
This quartz freeform has gorgeous, glassy clarity, being clear enough to read through, with inclusions of wispy white veils and reflective, silvery flakes. There are also some unique and interesting mossy green chlorite 'speckles' towards the wider end. It is a nice, sizeable piece and has been shaped and smoothed to an unusual, rounded, long 'arrow' form, and may be used for holding, for display or possibly as a massage wand. This is select grade quartz of the highest quality, expertly polished to a high lustre, ideal for discriminating crystal 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. Well-formed crystals deep within the Earth can reach colossal sizes, with some measuring several meters in length and weighing hundreds of kilograms. The largest documented single crystal of quartz was found near Itapore, Brazil, measuring 6.1 metres at its widest point and weighing in over 44,000 kilograms!
