Dolomite is a sedimentary carbonate rock that typically contains a high percentage of calcium magnesium carbonate. This mineral is often used for metaphysical purposes and is believed to have powerful spiritual properties. 

Today, dolomite is still prized for its healing properties. It is said to be helpful in easing anxiety and worry, and promoting emotional stability and peace. Dolomite is also believed to boost spiritual awareness and understanding. 

 It is said to be helpful in balancing emotional and mental energies, as well as providing strength and grounding during difficult times. Dolomite can also be used to cleanse and release negative energy from the chakras.

For these reasons, tumbled dolomite makes an excellent addition to any crystal collection.
