Pearls are formed in shellfish- especially oysters and mussels. They are formed as a natural defence against an irritant, such as a piece of grit. Layers of aragonite called nacre are secreted around the irritant and then it gradually builds up to form the pearl. Pearls vary in colour from white, white with a hint of pink, brown and even black. This depends upon the type of water and other ambient factors. Natural pearls have been found in Persian Gulf, Gulf of mannar in Indian Ocean and Red Sea for very long time. These days in Japan and China pearls are made through culture.
The chemical composition of pearls is Calcium carbonate with conchiolin and water. The specific gravity of pearls is 2.71; Refractive index of 1.53-1.68 and a hardness of 3. The crystal structure is Orthorhombic. The nearest chemical formula for pearls is Ca CO3,C3H18N9O11.nH2O.
Pearl has cooling and calming effects. It increases healing, vitality, fertility, longevity, digestive power of the body. It is known to decrease the effects of hepatitis, gallstones, bleeding, acidity, irritability, anxiety, malignant cancer, bloating and pain. It helps balance body fluids, female reproductive system, functioning of pancreas, liver and kidneys.
Pearl is the precious stone for Moon. The semi precious substitute for this is Moon Stone and Opal.
Moonstone is basically Orthoclase with a bluish white sheen and hence the name. It is Potassium Aluminium Silicate with hardness of 6 and specific gravity of 2.57 and Monoclinic crystal structure. These are found in Burma ,Sri Lanka,India ,Madagascar,Brazil,European Alps and Mexico.
Moonstone is a stone used for detoxification and fertility. It is very effective in menstrual problems and restores the normal cycle. It also helps alleviate PMS symptoms. It decreases effects of insanity, dropsy, leucorrhoea, bleeding, thirst, high blood pressure, pulmonary consumption, beestings and insect bites, malaria, yellow fever. It balances intestinal tract, lower spinal column, pancreas, pituitary glands. The stone is very effective in restoring the various body cycles.
Opal is hardened Silica Gel and contains 5-10 percent water. This is non-crystalline unlike other gems and with use it dries out and can have cracks. The Opal which shows iridescence is precious and for Moon white opal is used as substitute. It is Hydrated Silica Gel with hardness of 6,Specific Gravity of 2.10 and Refractive Index of 1.37-1.47 with structure being Amorphous. It is found in cavities in sedimentary rocks and Australia is the main producer of Opals. It is also found in USA, Mexico, Brazil and South Africa.
Opal is having cleansing properties. It improves vision and hearing. It is very good for headaches. It also adjusts and balances the nervous system
