A naturally form Amethyst crystal column, extracted as a whole geode, now precisely cut into a pair of geode caverns from the mine workings of Minas Gerais, Brazil. The two halves with a foot formed to each half, enable the wonderful crystal cavern to be showcased to the best advantage possible, revealing the numerous amethyst crystal points within.
Amethyst is naturally purple coloured quartz, the striking colour which is natural (some quartz are artificially heat treated to create various colours), is vivid in this particular specimen discovery, a delightfully deep purple hue.
The crystals created through the earth crust heat, vulcanism or magma. In this location particularly, the region of Minas Gerais, large and numerous with exceedingly good clarity, creating a dazzling array within the cavern. The play of light through the amethyst crystals is also bright and remarkable; the prismatic crystal terminations have an exceptional vitreous lustre. An excellent statement geode, a work of art formed by natural circumstances having taken perhaps aeons to form. Steady growth in the perfect conditional environment in South America, until the gases pocket, changed probably through earth movement, which terminates the process. Once the sealed pocket is ruptured, the crystal formation stops.
