What is the difference between different shape of tourmaline, jade , agate and bian stone disks used in the MediCrystal Gemstone mats and pads?
Tourmaline ceramic disks are the best for negative ion generation because we bake them with volcanic rocks, yellow clay, ochre, elvan, and other ores and minerals to enrich anion emission to a most healthy level of 700-1500 ions.
There is some difference between the different shapes of ceramic tourmalines and natural stones used in MediCrystal Gemstone mats. Flat stones may be more comfortable, while camber or dome-shaped stones provide more acupressure and concentrate ions and FIR rays in targeted spots. The flat stones distribute these ions and rays more evenly throughout the body.
The heat spectrum and positive effects produced by different stones can also vary greatly.
