Jadeite is an ornamental jade of value, beauty and rarity. The term jade is applied to two different metamorphic rocks that are made up of different silicate minerals: They are jadeite and nephrite. Only Myanmar found in jadeite of gemstone grade. Jadeite Jade crystallizes at pressure of 11-17kbar and temperature of 200-400°C corresponding to the depths of 30-60km in the mantle. High pressure and low temperature formation. Jadeite is a pyroxene mineral consisting of silicate of sodium and aluminium, occurring in the form of light green monoclinic crystals. It is the tougher and more highly prized variety of jade. The chemical composition:Sodium Aluminum Silicate (NaAlSi2O6).The hardness of 6.5 to 7 ( Mohs’ scale ).The specific gravity of 3.28 to 3.40. Refractive index of 1.65 to 1.66. Colours with Red, Yellow, Green, Lavender, Black, White.
