Actinolite Included Quartz Semi-Polished Standing Point - 41mm, 32g
Locality - Madagascar Size – 41 x 35 x 14mm Weight – 32g
This quartz standing point features unique, heavy inclusions of mossy green actinolite strands within. It is a very characterful piece that has been expertly shaped to a classic, tabular crystal form and polished to a high lustre, with a natural, rough 'pit' left intact below the polish line, and cut at its base to stand freely.
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.
