Tips on Gemstone - Jade

Jade is an ornamental stone. The term jade is applied to two different rocks that are made up of different silicate minerals. Nephrite jade consists of the calcium- and magnesium-rich amphibole mineral actinolite (aggregates of which also make up one form of asbestos). The rock called jadeitite consists almost entirely of jadeite, a sodium- and aluminium-rich pyroxene. display of several solid model plots

Care of Gemstone
Use mild soap and warm water is the easiest and safest cleaning solution. Use soft cloth to dry.
Avoid bumping on hard surfaces as gemstones are delicate.
Do not expose gemstone to sunlight for a long time, or it may expand and the quality will change. Keep it in an area of humidity to protect it from over-drying.
It is most desirable to store gemstone in a fabric-lined case or in a box with dividers or separate compartments to avoid the gemstone surface being scratched by other hard objects, as well as by each other.
