Most people have the concept that the color of jade is green.
In fact, Jadeite Jade comes in all hues of color. The chemical composition of Jadeite Jade is Sodium Aluminum Silicates (NaAlSi2O6) and in its pure form it is whitish or colorless. Over the hundreds of millions years of its formation, the environment on which the crystals grow is subject to earthquakes, volcanic activities, atmospheric changes, tectonic plate movements within the earth crust and the mantle, cooling and heating up of the earth’s surface and other environmental factors of rain and sun. These activities account for the numerous fractures, cracks and veins within a rough boulder of jade.
When a trace of chromium (Cr 3+) seeps inside a jade boulder, that area becomes chromium green. Lavender is due to the trace elements of vanadium and manganese. Oxidation on the surface of the Jadeite Jade over the millions of years of its crystallization renders the stone an ochre reddish brown due to ferrous oxide. Often a combination of colors can be found in a Jadeite Jade piece ranging from dark to light green, black to white, red to brown and yellow, light lavender to bluish gray and irregular patches of green color, which is term as mottled.
The most pricey color is emerald-green Imperial Jadeite, colorless icy jadeite and vivid color lavender Jadeite Jade.
