Blue Calcite
Global Mining Sites
Calcites are found on nearly every continent, but only found in a few places on earth. Although it’s found in large masses and is quite common, a majority of Blue Calcite come from Mexico. The deepest colour blue specimens famously come from South Africa.
History
Blue Calcite was discovered in 1669 by Rasmus Bartholin. In 1836, Johann Carl Freiesleben started to call the stone “lime”, a name taken from the Greek word “khalx”.
The stone has been used since the ancient times according to experts. The Egyptians used it to make small decorative objects such as figurines and statuettes. A specimen was even found on a Viking ship in 1592. The mineral was used as a compass depolarising sunlight.
Legends associated it with magical practices and witchcraft as it was believed to be used by spellcasters.
Appearance
Calcite is found within limestone and marble, two common stones that make up a large portion of the earth’s crust. Calcite is also a primary mineral component in cave formations.
Calcite is vitreous in appearance and can be found in a range of colour from white or colourless to red, green, yellow, blue, and orange. Calcite and Aragonite actually share a chemical composition, but their different crystal structures are what separates them.
