About Jadeite - History and Introduction
Jadeite is a pyroxene mineral and one of the two types of pure jade. The other is known as nephrite jade. Jadeite is the rarer of the two jades, and as a result, it is considered to be more precious and valuable. The most valuable form of jadeite is a striking and even emerald green known as "imperial jadeite". The history of jadeite goes back several thousand years when it was first used to make weapons and tools because of its toughness. Jadeite was highly prized by the Mayans and Aztecs, in fact the name "jade" originates from the Spanish "piedra de ijada", meaning "stone for the pain in the side". It was thus named after Spanish explorers noticed natives of Central America holding pieces of jade to their sides to cure ills. In Chinese, jade is known as "yu", which means "heavenly" or "imperial". Therefore, it is considered to be the imperial gem in Chinese culture. In China, jade was found in the tombs of Shang kings.
Identifying JadeiteBack to Top
Jadeite can be distinguished from other similar materials, such as nephrite, by its hardness and density. There are a lot of other materials fraudulently sold as jadeite and it is difficult to identify jadeite by outside appearance. The most reliable method of identifying jadeite from other substances is by testing its specific gravity. A simple test to distinguish jadeite from nephrite is a chime test. Nephrite emits a musical tone when it is struck, whereas jadeite does not.

Nephrite is the other type of jade that can easily be confused with jadeite. Nephrite is the most common form of jade and is softer than jadeite, at 6 - 6.5 on the Mohs scale of hardness. Nephrite can also be distinguished from jadeite by its lower specific gravity and different crystal structure. Nephrite also differs from jadeite in its chemical composition; nephrite is calcium magnesium iron silicate, whereas jadeite is sodium aluminum silicate.

Serpentine looks similar to jadeite, but serpentine is softer, less dense and feels greasy to the touch.
