Zebra calcite rough stones from Mexico.
Although the black and white layers in zebra calcite make this a distinctive and fascinating stone, these patterns are relatively common and can be found in many rocks and minerals.
Several websites state zebra calcite is a new find from Mexico. Although that's true about material from Mexico, this type of layered calcite has been known and studied extensively by geologists for many years.
On some metaphysical-related websites, zebra calcite is promoted as a relatively hard stone that's safe to soak in water. Both statements are incorrect.
Like all types of calcite, zebra calcite grades 3 on the Mohs scale of hardness, which means it's very soft.
Calcite should not be submerged in water and should not be allowed to get wet. In warm water, calcite precipitates and in colder water, it gradually dissolves.
These zebra calcite rough stones make striking display pieces. They have been coated with a fine, colourless resin which offers some protection.
