Extremely valuable ✨ [Stalagmite] Gifu Prefecture, Japan, Mineral Raw Stone, Stalagmite 1 Thank you for viewing!✧︎* This is a very rare stalagmite, which is hard to come by, even among stalactites.✨ 'Features' Stalactites are deposits formed inside caves, and are white or gray icicle-like precipitates hanging from the ceiling of a limestone cave. Stalactites are formed when rainwater or groundwater containing carbon dioxide flows into caves in limestone regions, dissolving the limestone. The water drips and the calcium carbonate precipitates. Stalactites come in various shapes, such as those that hang down like icicles and those that grow from the ground like bamboo shoots (stalagmites). Depending on the environment, they grow only about 1 cm in 100 years on average. Stalactites are carbonate sediments mainly composed of calcium carbonate, and because the crystal growth rate is relatively slow, it is usually said that "it takes 200 to 500 years to grow 1 cm."
