7.2" Pink Quartz Chalcedony Stalactite Formation - India

Pink Quartz Chalcedony Stalactite Formation - India #237753

This is a gorgeous, 7.2" tall, pink chalcedony stalactite formation, collected from Maharashtra, India. This specimen would have formed from the ceiling of a cavity within the host rock. The natural pink color of this specimen can be attributed to impurities in the underlying chalcedony layers. It sits nicely on a flat surface without the need for a display stand.

Chalcedony is any microcrystalline variety of silica composed of very fine intergrowths of quartz and mogánite: microcrystalline minerals have microscopic crystals that cannot be observed by the naked eye. Both quartz and mogánite have the same chemical formula SiO2 (silicon dioxide), but different crystal structures. When free from impurities, chalcedony is colorless and transparent. Depending on impurities present during formation, chalcedony can form in a wide variety of colors including red, yellow, green, blue, purple, grey, white, and numerous hues in between. Chalcedony is quite hard at 7 on the Mohs Hardness Scale: this matches its main component quartz, which is the benchmark mineral for the scale at 7.
