Amethyst Stalactite Slice I
Amethyst Stalactites are formed beginning with one drop or mineral rich water, high in calcium carbonate. When the fist droplet falls it forms a ring like structure of calcite. Over time, droplet after droplet, the calcite layers form an agate center and when the time is right amethyst crystals begin to grow. They can be found with amethyst of the lightest lavender to deep purple crystals.
