In this Crystal Tree article, we take a look at the different types of Jade and its history, as well as where Jade is found. Wondering what Jade is? Keep reading to find out!

Jade has been used by civilizations since the Stone Age, trading carved objects as currency, making weapons, jewellery and decorative pieces. Historically, China has valued Jade for both religious and medicinal properties, with Jade objects and artworks being highly prized culturally. The Olmecs, Maya, and Aztecs of Meso-America made ceremonial objects and jewelry from jadeite. They valued this material more than gold. Its name comes from the Spanish piedras de ijada, meaning “stone of the loins” as Jade was believed to heal kidney ailments.

WHAT IS JADE?

Jade is actually the name for two different silicate mineral forms, Jadeite and Nephrite. These two minerals can be identical in appearance and are similar in their physical properties. They were thought to be one mineral type until 1863, when it was discovered that they are scientifically different. It is said, however, that the Chinese knew of two different forms more than a century earlier. Yu was the Jade material they had traditionally carved (Nephrite). Fei-ts’ui was the name for the intense green Jade material that began to enter China from Burma (Myanmar) in the mid 18th century (Jadeite).

Jade is mined in many locations around the world. Both Jadeite and Nephrite are found in Russia, China, and Guatemala. Nephrite deposits of varying quality have been discovered in both the Swiss Alps and New Zealand. Western Canada has yielded some beautiful dark green stones termed “Canada Jade.”

What is Jadeite Jade

Jadeite is a sodium aluminum silicate, composed of tightly packed microscopic crystals. Jadeite is not as dense as Nephrite and is more prone to chipping. Jadeite Jade is the rarer and more valuable form of Jade. It is most prized in its pure green variety, but can be found in many colors ranging from red, pink, black, brown, white, and even violet with variations of colors overlapping one another.

The most in-demand Jadeite stones can be sourced back to Myanmar, formerly Burma, and are known as “Burmese Jade.” These have become exceedingly rare and valuable due to the country’s political upheavals and trade restrictions.

What is Nephrite Jade

Nephrite is a calcium magnesium silicate, composed of extremely dense mineral fibers that are interlocked and very tough. Nephrite is softer and more prone to scratches. It is also the more common of the two.
