Natural Madagascan Green Chlorite Quartz Cluster - 89mm, 397g
Locality - Madagascar Size – 89 x 68 x 64mm Weight – 397g
This quartz cluster from Madagascar has nice mossy green chlorite inclusions throughout the sturdy matrix and inside the glassy clear, tightly packed crystal stems. One of the central crystals shows impression indents from other intergrown terminations that are now long gone. It is a unique specimen with plenty of visual interest points, ideal for display. Despite a few minor fractures on the terminations, these are not noticeable from afar and it is still an attractive piece.
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.
