Cayman Crystal Caves have formed over millions of years. Fossilized shells and animal life in the caves show us that at one time, the mass now containing the caves was all located under the sea. Over time, as sea levels changed and land began to rise, rooms began to form through water erosion, making caves. Within these rooms spectacular stalagmite and stalagtite crystal structures began to form, as rain water dripping through the limestone ceiling of the caves left calcium deposits behind. The caves are still today continuing to evolve. The process of stalagmite and stalagtite formation occurs as rain water becomes slightly acidic when it first travels through surrounding plants, earth and other organic matter. This acidic water disolves part of the limestone as it seeps through the earth, and re-deposits microscopic calcium layers, as the water drips from the cave celings. Over time these deposits collectively form the crystal structures.
