BLUE SAPPHIRE

Blue Sapphire is basically Corundum and comes in many other colours as well. But traditionally sapphire is associated with blue colour only. The chemical composition is Aluminium Oxide with a formula of Al2O3.Good quality Blue Sapphire is found in Burma, Sri Lanka and India. The best Indian Sapphire is cornflower blue and is found in Jammu and Kashmir. Montana in USA also produces blue sapphire . Cambodia ,Brazil,Kenya,Malawi and Colombia also produce this sapphire. The sapphire has hardness of 9 ,specific gravity 4.00,refractive index 1.76-1.77 with a Trigonal crystal structure.
The stone is said to be increasing eyesight, longevity, blood flow to organs. It helps decrease rheumatism, sciatica, neurology, epilepsy, hysteria, tumour, reduces fat, arthritis, nerve pains, mental illness, petrochemical and radiation miasms, excessive bleeding, emotional pain and trauma, haemorrhage. It provides balance to intestinal tract, pancreas, lower spinal column, heart, blood, and adrenals.
Blue sapphire is the precious stone for Saturn. The semi precious substitute is Turquoise and Lapis lazuli.
Turquoise is one of the first gemstones mined and varies from sky blue in colour to greenish. It is commonly found in microcrystalline, massive form, usually as encrustations or as nodules. Sky blue turquoise from Iran is the best, but in Tibet a greener variety is found. Mexico and USA also produce greener variety. Chile ,Australia and England(Cornwall) also produce. The distinct blue colour is due to presence of copper and traces of Iron.
It has hardness of 6,specific gravity of 2.80,Refractive Index 1.61-1.65 and is chemically Hydrated copper aluminium phosphate. The crystal structure is Triclinic and the formula is CuAl6(PO4)4(OH)8.5H2O.
Turquoise has amazing property for helping in disorders of female reproductive system. It increases eyesight, tissue regeneration and circulation. Turquoise is very effective in headaches and migraines. It also decreases fever, cataracts, effects of environmental pollution, anorexia, and stress. It balances circulation, tendons, ligaments, throat, thymus gland, and nerves.
Lapis Lazuli is a Blue rock made up of several different minerals, including Lazurite, Sodalite, hauyne, Calcite and pyrite. The colour of Lapis lazuli varies as per composition but the intense blue variety with minor patches of white calcite and brassy yellow pyrite is the best quality. It is usually found as boulders or within limestones.The best quality lapis lazuli is from Afghanistan. Argentinian stone is also of very high quality. Some different shades of blue are also found in USA and Canada.
It has hardness of 5.5,specific gravity 2.80.refractive index 1.50 with Variable crystal structure. The formula is (Na,Ca)8(Al,Si)12O24(SO4)Cl2(OH)2.
Lapis lazuli increases strength, virility, vitality, oxygenation of blood, mitosis, hearing and immune system. It decreases poison, fever, depression, melancholia, neuralgia, spasms, tonsillitis, anxiety, Hodgkin’s disease. Cancer of the larynx, autism, urinary troubles, tuberculosis, haemorrhoids, jaundice, diabetes, insomnia, neurosis, vertigo and dizziness. It helps in balancing emotions, vocal cords, thyroid, esophagus, bronchial tract, bone marrow, skeletal system and Eustachian tube.
