Description
Beautiful polished aqua blue/green calcite sphere from Balochistan, Pakistan. This material has been known to contain a mix of both calcite & aragoniteboth minerals have the chemical formula of calcium carbonate, but have different atomic structures (known as polymorphs). Depending on the pressure & temperature, calcium carbonate may prefer to arrange itself either as aragonite or calcite, & over time one may convert to the other if the conditions in temperature & pressure change. Although it is mined in Pakistan this material goes by "Caribbean" calcite due to the ethereal light aqua blue colour, reminiscent of a pristine tropical beach. Calcite in its pure form (CaC03) is clear or white. Most sources agree that the blue colour in blue calcite is caused by natural ionizing radiation, such as gamma rays. Specific piece measures approximately 5 cm in diameter, 160 g. This sphere does not come with a stand. This material is soft & there may be slight chips/nicks in the polishing. All photos were taken under a white LED light & have not been edited for light or colour; colour may look more muted under standard indoor lighting. Keep in mind that in different lighting/indoor lighting the colours may vary. Feel free to message me with questions or more photo requests!
