Yellow Hematoid Included Quartz Polished Standing Point - 60mm, 54g

Locality - Madagascar
Size – 60 x 30 x 17mm
Weight – 54g

This polished quartz point features nice tangerine yellow hematoid 'cloud' inclusions throughout one side with a clear centre and a bright, silvery reflective veil in its base that displays a dazzling, vivid rainbow when viewed in strong lighting (as photographed). There are also a couple of small, ingrown crystals in its back. It has been expertly shaped to a classic, sharply terminated tabular crystal form, polished to a high lustre and can stand freely on its base.

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.
