Garnet is encountered in numerous colours like red, orange, green, blue, brown, black, pink and colourless. Blue Garnet is the sporadic one among all. It varies colour from blue- green in daylight to purple in luminous light, as allusively higher gob of vanadium. Other several varieties of colour wavering garnet also prevail. Its species light hauling properties can varies from gemstone- quality transparent to the opaque ones propitious for industrial purposes as abrasive. They take shape in form of a cubic structure with three axes of equal length and mutually perpendicular to each other. They do not show cleavage rather they collapse under stress or pressure and irregular pieces are generated. Due to reinforced atomic bonds this group of mineral shows allusively a range of 6.5 to 7.5 on the Mohs scale. It quickly gets retorted to strong neodymium magnet which makes for us easy to distinguish it from other transparent gemstones.
The garnet is essentially good for the wellbeing of thyroid and spleen. It not merely cleanses but also purifies both when held over the area. It also serves for the purpose of spiritual relaxation. It will reenergize you and will inculcate holistic approach in you. It has remarkable magical properties. It will not merely avail you with the protection shield from the dissenting energies but will also ricochet it back to its source of origin.
Its special properties are that it can curb lungs, blood or infections related problems up to a great extent. It embellishes your sexuality and sensuality expressions. It recharges you with new energy filled with the warmth of optimism and new ray of hope.
Garnet sand can be used as an abrasive and water filtration media.
Garnet gemstones / crystals are found in some of the countries of world are: Australia, Austria, Canada, Czech Republic, France, Germany, Greece, Iran, Italy, Japan, Lesotho, Mexico, Namibia, Norway, Portugal, Russia, Switzerland, Tanzania, Turkey, USA, Zimbabwe
