Jade: The Stone of Heaven

Few gemstones have a history as long, complicated, and culturally significant as jade.

For thousands of years, people have carved it into weapons, ceremonial objects, jewelry, religious symbols, and works of art. In China, jade became associated with virtue, immortality, status, and the heavens. In Mesoamerica, jadeite was prized by the Maya and Aztecs. And throughout many cultures, its extraordinary toughness made it useful for objects that needed to survive for generations.

Yet one of the most interesting things about jade is that “jade” isn’t actually the name of a single mineral.

It describes two very different materials: jadeite and nephrite.

What Is Jade?

Gemologists use the word jade primarily for two materials: jadeite and nephrite. Both are extremely tough, fine-grained rocks made up of interlocking mineral crystals, which is what gives them their remarkable resistance to breaking and chipping. 

Jadeite and nephrite can look remarkably similar, particularly in shades of green, but they are chemically and structurally quite different.

Jadeite is a pyroxene mineral with the chemical formula NaAlSi₂O₆. Nephrite is an aggregate of amphibole minerals, primarily tremolite and actinolite. 

Jadeite is generally considered the more valuable material, particularly when it possesses the exceptional color and translucency associated with fine Burmese jadeite. But nephrite has an equally fascinating history—and in China, it was the original “jade.”

Nephrite: The Original Chinese Jade

For thousands of years, the jade revered in China was nephrite.

Chinese artisans were working nephrite more than 5,000 years ago, creating everything from tools and weapons to elaborate ritual objects and ornaments. The material’s extraordinary toughness allowed craftsmen to carve it into complicated shapes and extremely thin sections without it shattering easily. 

This toughness is one of jade’s great paradoxes. Jade is not exceptionally hard compared with gemstones such as sapphire or diamond. Jadeite measures approximately 6.5–7 on the Mohs scale, while nephrite is around 6–6.5. But both are exceptionally resistant to breaking because of their interlocking fibrous or granular structures. 

That distinction between hardness and toughness is important.

A diamond is extremely hard, meaning it is difficult to scratch. Jade is comparatively softer, but extraordinarily difficult to break.

For an ancient sculptor working without modern tools, that was an extraordinary advantage.

Jadeite Arrives in China

The story changes dramatically in the eighteenth century.

Jadeite from what is now Myanmar began reaching China during the late 1700s. Chinese craftsmen quickly recognized that this new material could possess exceptionally vivid green color and remarkable translucency. 

The Chinese already had thousands of years of jade-carving tradition behind them. They applied that tradition to this new material, and jadeite eventually became enormously important to the Chinese jewelry market.

The distinction between the two types of jade is therefore relatively modern from a Western gemological perspective. For centuries, Chinese jade culture had simply encompassed the material traditionally known as yu, with nephrite at its heart.

The arrival of Burmese jadeite added a new—and extraordinarily valuable—chapter to that tradition.

Why Is Jade So Important in Chinese Culture?

Jade’s significance in China goes far beyond jewelry.

It became associated with qualities such as purity, virtue, wisdom, loyalty, and immortality. Confucius famously compared the qualities of jade to those of the virtuous person, helping establish the stone’s association with moral character as well as beauty. 

Jade was also deeply connected with heaven and the afterlife.

One of the most recognizable forms is the circular jade disc known as a bi, traditionally pierced through the center. The bi was associated with heaven and appears in Chinese ritual objects dating back thousands of years. 

Jade was also used for objects associated with political authority. Imperial seals, ceremonial objects, burial objects, and other symbols of rank were carved from it.

Some Han Dynasty rulers were even buried in elaborate jade burial suits, constructed from hundreds or thousands of jade pieces connected with gold or other materials.

The stone was beautiful, but its meaning was much larger.

Jade was thought to endure.

And therefore it became associated with things that were meant to endure: virtue, power, memory, and life beyond death.

Jade Around the World

Although China developed perhaps the most elaborate jade culture, it was far from the only civilization to value the material.

In Mesoamerica, the Maya and Aztecs prized jadeite for jewelry, ornaments, ceremonial objects, and religious artifacts. The stone was associated with life, fertility, water, and power. 

The Spanish conquistadors encountered enormous quantities of gold in the Americas, but they also encountered something they considered mysterious and valuable: green stones that Indigenous people used for objects and sometimes held against the body for medicinal purposes.

The Spanish expression piedra de ijada, meaning roughly “stone of the flank” or “stone of the side,” eventually gave rise to the word “jade.” The name came from the belief that the stone could relieve pain in the side or kidney area. 

The word itself is therefore a little piece of colonial history.

The stone had existed for thousands of years.

The name “jade” came much later.

What Makes Jade Valuable?

Jade is unusual because its value isn’t determined in quite the same way as that of a faceted gemstone.

A diamond is largely evaluated through the familiar considerations of color, clarity, cut, and carat weight. Jadeite is more complicated.

According to GIA, the three most important quality factors for jadeite are, in order, color, transparency, and texture. 

Color

Color is the most important factor.

Although jadeite occurs in many colors—including lavender, white, yellow, orange, brown, black, and gray—the most valuable is an intense, vivid green known as Imperial jade. 

The finest Imperial jade is an intense, saturated green with excellent translucency and a remarkably even appearance. It should look vibrant rather than gray or dull.

Other descriptive terms encountered in the jade trade include “kingfisher,” “apple,” and “moss-in-snow,” each referring to particular color combinations or patterns. 

Transparency

Fine jadeite isn’t necessarily completely transparent.

In fact, the most desirable material is generally semi-transparent, allowing light to penetrate the stone and giving it a soft, glowing appearance. 

This is one reason photographs can sometimes fail to capture the beauty of fine jade.

A piece can look relatively opaque in one setting and suddenly appear luminous when light passes through it.

Texture

Texture refers to the fineness and evenness of the jadeite’s underlying crystal structure.

Fine-textured jade has a smooth, almost velvety appearance and polish. Coarser material can appear more granular or uneven.

The combination of fine texture and translucency is particularly desirable.

Jade Isn’t Usually Sold by the Carat

Another interesting difference between jade and many other gemstones is that fine jadeite is often sold by the piece rather than simply by weight.

A large Imperial jadeite bangle, for example, isn’t necessarily worth more simply because it weighs more. The cutter has to consider color, translucency, texture, fractures, shape, and how much of the original rough can be preserved.

For top-quality jadeite, even relatively small differences in size can produce enormous differences in price. 

This is particularly true of bangles and cabochons, where the quality of the entire piece must be considered.

The Mystery of Jade Bangles

The jade bangle is perhaps the most iconic form of jade jewelry.

The tradition of carving bangles from jade is ancient, and the earliest Chinese examples were made from nephrite. GIA notes that the style is thought to date back at least 4,000 years. 

A jade bangle is usually carved from a single piece of rough.

That means the cutter has to find a section of material large enough to accommodate the entire circle. Any major fracture, discoloration, or undesirable area can make the rough unsuitable.

The result is a fascinating object: there is no clasp, hinge, or separate setting. The stone itself is the jewel.

And because a traditional bangle is meant to fit fairly closely around the wrist, the finished piece can be surprisingly difficult to put on and remove. 

“A,” “B,” and “C” Jade

If you have ever shopped for jade, you may have encountered terms such as “A jade,” “B jade,” and “C jade.”

These aren’t quality grades in the same sense as “excellent” or “poor.” They refer primarily to treatment.

“A jade” generally refers to jadeite that is untreated, apart from traditional finishing such as polishing and, depending on the classification system, waxing.

“B jade” has typically been chemically bleached to remove undesirable coloration and then impregnated with polymer resin.

“C jade” has been dyed.

B+C jade can also refer to material that has undergone both processes. 

These treatments can make lower-quality jadeite look dramatically better, which is why they matter so much to collectors.

A vivid green stone may look extraordinary under display lighting, but its appearance and durability can be very different if it has been heavily treated.

For an important purchase, an independent gemological report is therefore worthwhile.

Why Jade Can Be So Expensive

The very finest jadeite can be extraordinarily expensive.

This is partly because truly exceptional material is extremely rare. Fine jadeite needs the right combination of color, translucency, texture, size, and lack of significant fractures. Finding all of those characteristics together is extraordinarily difficult.

Demand also plays an enormous role.

Fine jadeite has a particularly strong cultural and collecting market in China and throughout the Chinese diaspora, and GIA notes that demand for top-quality material has historically outpaced supply. 

At the highest level, jadeite has achieved prices that rival the world’s most valuable diamonds.

One of the most famous examples is the Hutton-Mdivani jadeite necklace, created by Cartier from a remarkable strand of translucent emerald-green jadeite beads. When Sotheby’s sold the necklace in 2014, it realized $27.4 million, setting an auction record for jadeite jewelry. 

That price can seem astonishing until you understand just how difficult it is to assemble a matched strand of exceptional jadeite beads.

Every bead must have compatible color, texture, transparency, size, and overall appearance.

Finding one exceptional stone is difficult.

Finding many that look as though they belong together is considerably harder.

Jade as an Investment

Because exceptional jadeite can command enormous prices, it is sometimes described as an investment gemstone.

There is truth behind this, but it is important to be cautious.

Fine jadeite is an expert market. Treatments can be difficult to identify without laboratory testing, and two pieces that appear similar to an inexperienced buyer can have radically different values.

Even among untreated jadeite, quality varies tremendously.

The safest approach is to think of jade first as a gemstone and work of art rather than assuming that any piece labeled “jade” will appreciate in value.

For significant purchases, documentation of the material, treatment status, and—when relevant—geographic origin is especially important.

A Stone That Rewards the Hand

One of the most beautiful things about jade is that it was never simply a stone for setting into jewelry.

It is a material meant to be handled.

Chinese jade carving developed an extraordinary vocabulary of symbolic forms: dragons, phoenixes, bats, peaches, flowers, animals, mountains, clouds, and mythical creatures could all carry particular meanings. The translucency, color, and texture of the stone became part of the artwork rather than merely a background for it.

The finest carvers also learned to work with the natural characteristics of the rough rather than simply cutting them away.

A patch of green might become a leaf.

A dark inclusion might become part of an animal.

An irregular shape might inspire the entire composition.

In this sense, jade carving is a conversation between the artist and the stone.

Jade’s Extraordinary Toughness

There is another reason jade has survived so successfully through history.

It is remarkably difficult to destroy.

Neolithic cultures used nephrite to make axes and other tools because its exceptional toughness allowed it to withstand impacts that would shatter many other stones. 

Even today, jadeite and nephrite are relatively resistant to breaking and chipping, although they can certainly be scratched and damaged. GIA recommends ordinary care and notes that heat and warm acids can damage jade, while treated material may require additional caution. 

That toughness helps explain why ancient jade objects can survive thousands of years.

A delicate glass ornament might disappear.

A jade carving can remain almost unchanged.

A Stone of Memory

Perhaps more than almost any other gemstone, jade has always been about continuity.

A jade ornament can outlive its maker.

A bangle can pass from grandmother to daughter to granddaughter.

A carved figure can survive a dynasty.

A burial object can remain intact long after the person for whom it was made has been forgotten.

And the stone itself does not seem to age in the way other materials do.

That may be the deepest reason for jade’s enduring appeal.

It is beautiful, but beauty alone does not explain its history. Jade is difficult to break, difficult to exhaust, and capable of being carved into objects that can survive for thousands of years.

From prehistoric tools to imperial treasures, from ancient ceremonial objects to Cartier’s legendary jadeite necklace, jade has always occupied an unusual place between nature and art.

It is not merely a gemstone.

It is a material with a memory.

And for thousands of years, people have found ways to give that memory a shape.
