Dog tooth calcite Size-8.3cm x 7.1cm x 4cm Weight-179g You will receive the item in the photo Dogtooth calcite (also known as dogtooth spar) is a unique scalenohedral crystal habit of the mineral calcite. It gets its name from its sharply pointed elongated crystal chape that resembles a dogs canine teeth. Mineral class: Carbonate Crystal system: Trigonal Hardness: 3 on the MOHs scaleRock formation: dogtooth calcite does not form its own massive rock type, but instead develops as speleothems (cave formations) or as linings inside cavities.It’s primarily found in underground cave systems,hydrothermal veins and fractures within paleozoic limestones.It occurs when water supersaturated with dissolved calcium carbonate seeps into underground spaces. When carbon dioxide escapes the water the soild calcium carbonate precipitates to create these spiky crystalline crystals. They are frequently found growing on a limestone or marble matrix alongside minerals like quartz, fluorite or sphalerite.
