Hot stone reflexology and massage uses basalt stones for the heat application. These are the beautiful result of volcanic eruptions. It is molten lava that has solidified under intense heat and pressure. Basalt stones are typically rounded and smoothed by the motions of the water that they are found in. The ocean or rivers tumble them enough to be able to use in their natural state. The basalt stones that I use come from a volcanic river bed in Peru. They are purchased fairly using local trade laws.

Basalt is chosen for hot stone therapy because it retains heat well and is non-explosive (will not crack in heat). Since basalt is formed from molten lava and molten lava is rock that was heated so much it became liquid, there is a lot of strength, fire and power contained within basalt. Some say it has healing properties of its own.

Marble is used for the cold application. This cannot be used in its natural state, it needs to be shaped and polished so that it can be used on bare skin. The marble I use comes from the Hebei province of China (known for the Great Wall of China!). Marble is often used by stone therapists for grounding and calming, and it is said to enhance the power of serenity.
