ORIGIN OF JADE GEMSTONE

The name “Jade” dates back to the time of the conquest of the Americas: it derives from “piedra de ijada” (stone of colic), this name is known from 1565, while another name that was given at that time was “Stone of the kidneys” translated into Latin becomes “Lapis Nephriticus” (and hence Nephritis). In any case these nomenclatures indicate the link that the Spanish conquerors made between the shiny stones of Jade and the kidneys.

2. CHEMICAL COMPOSITION OF JADE

The Jade is composed of particular silicate minerals distributed in a structure made of very fine granules and interlaced fibers that make it very resistant. Jade is opaque, that is, impenetrable to light.

4. HISTORY OF JADE

More than any other gem, Jade is imprinted in the heart of China’s culture and under its influence throughout Southeast Asia. Considered as a real gem, Jade began to be extracted as early as 6,000 years BC It was called by the ancient Chinese the “Gem of Heaven” because it was associated with immortality and the power to establish a bridge between heaven and earth. . There are two varieties of Jade – Jadeite (group of alkaline pyroxenes) and Nephritis (group of amphiboles). Until 1863 both varieties were called Jade.

It was thanks to the French minerologist Alexis Damour discovery that the Chinese Jade (Nephritis) and the Burmese Jade (named by him Jadeite) belong to different minerals, but with similar properties and appearance.

Jadeite has a brief history and was never particularly required until the 18th century. The most beautiful specimens, of great purity and an intense emerald green were so coveted by the Chinese emperors that it was given the name of Imperial Jade. The Jadeite comes in several colors: blue, brown, cream, green, gray, lavender, orange, red, violet, white, yellow and combinations of these colors, even in the form of spots. The reddish coloration of the Jadeite is due to the presence of iron debris. Its intense greens are instead due to chromium. Nephritis presents a smaller range of colors: brown, gray, yellow, white. Both the spots and the red, yellow and brown lines are due to an oxidation process.
