While nephrite was the traditional jade of China for millennia, the eighteenth century saw the introduction of a new material that would transform jade culture: jadeite from Burma (Myanmar). Harder, more translucent, and available in a wider range of colors than nephrite, jadeite quickly became the most precious jade variety, commanding prices that exceed those of diamonds.
Discovery and Introduction
Geological Characteristics
Jadeite is a sodium aluminum silicate, distinct from nephrite's calcium magnesium silicate composition. This difference gives jadeite different properties:
Hardness: Jadeite measures 6.5-7 on the Mohs scale, compared to nephrite's 6-6.5. This makes jadeite more resistant to scratching but also more difficult to carve.
Density: Jadeite is denser than nephrite, feeling heavier in the hand. Specific gravity ranges from 3.30-3.38, compared to nephrite's 2.90-3.02.
Refractive index: Jadeite has a higher refractive index (1.66) than nephrite (1.60-1.62), giving it greater brilliance and "life."
Structure: Jadeite forms interlocking granular crystals that can be extremely fine, allowing high polish and detailed carving.
Colors: While nephrite occurs primarily in white and green, jadeite appears in virtually every color: green, lavender, white, yellow, red, brown, black, and combinations thereof. This color range expanded the possibilities for jade jewelry and carving.
The Colors of Jadeite
Jadeite color significantly affects value:
Imperial green is the most valuable color—a vivid, saturated emerald green with high translucency. The finest imperial green jadeite commands prices exceeding those of diamonds on a per-carat basis.
Apple green is a lighter, brighter green that is also highly valued. It lacks the depth of imperial green but has cheerful appeal.
Lavender (zilian) is the second most valuable color after green. Fine lavender jadeite has a delicate, romantic quality that is particularly popular for jewelry.
White jadeite, when fine and translucent, is valued for its purity. It lacks the color premium of green or lavender but can be exquisite.
Multi-color jadeite combines different colors in a single piece. "Spring colors" (chun) combines green and lavender; other combinations create distinctive effects.
Lesser colors—brown, gray, pale yellow—are less valuable but may be preferred for certain carvings or may be treated to improve their appearance.
Mining and Trade
Jadeite mining in Burma is concentrated in the Kachin State, particularly around Hpakant. The mines produce both primary deposits (hard rock) and secondary deposits (river gravels). The finest material traditionally came from river gravels, where natural weathering had removed lower-quality material.
The jadeite trade has always been complex and often dangerous:
Mining conditions are hazardous. Both large-scale industrial mining and small-scale artisanal mining involve significant risks. Landslides, accidents, and health hazards from dust are common.
Political involvement has characterized the jade trade. The Burmese military, ethnic militias, and criminal networks have all controlled aspects of the trade. Revenue from jade has fueled conflict in northern Burma.
Smuggling has been common due to trade restrictions and taxation. Much Burmese jadeite reached China through unofficial channels.
The Yunnan connection: The Chinese city of Ruili, on the Burmese border, became the primary trading center for jadeite entering China. From Ruili, rough jadeite was distributed to cutting and carving centers, particularly Guangdong province.
Processing and Carving
Rough jadeite requires expert evaluation and processing:
Rough evaluation is a specialized skill. Experts examine the exterior of jadeite boulders to predict internal quality. The "skin" of the boulder provides clues about what lies within, but surprises are common.
Cutting requires diamond saws and considerable skill. The cutter must plan to maximize value, orienting the cut to take advantage of color and avoid flaws.
Carving jadeite is more difficult than carving nephrite due to its hardness. Diamond tools are essential. The carver must work carefully, as mistakes are difficult to correct.
Polishing brings out jadeite's natural luster. Fine jadeite takes a high polish that enhances its depth and brilliance.
Jadeite Jewelry
Jadeite is particularly valued for jewelry:
Bangles are the most traditional form of jadeite jewelry. A solid jadeite bangle represents the ultimate luxury, requiring a large piece of high-quality rough. Bangles are believed to protect the wearer and bring good fortune.
Beads and necklaces showcase jadeite color and translucency. Matching beads for a necklace requires finding multiple pieces of similar quality from the same rough.
Cabochons are domed, polished pieces set in rings, pendants, and earrings. The cabochon cut maximizes the display of color and translucency.
Carved pendants combine jadeite beauty with symbolic meaning. Traditional subjects—Buddhist deities, auspicious symbols, natural forms—are popular.
Settings for jadeite jewelry are typically gold, often with diamond accents. The warm color of yellow gold complements green jadeite; white gold or platinum suits lavender and white jadeite.
Treatment and Enhancement
Most jadeite on the market has been treated to improve its appearance:
Type A jadeite is natural, untreated material. This is the most valuable type, particularly if fine quality.
Type B jadeite has been bleached to remove brown coloring and impregnated with polymer to improve transparency. This treatment is common and must be disclosed. Type B jadeite is less valuable than Type A.
Type C jadeite has been dyed to improve or change its color. Dyeing can create artificial "imperial green" from pale material. Type C jadeite is much less valuable than natural material.
Combination treatments apply multiple processes. Type B+C jadeite has been both bleached/impregnated and dyed.
Testing by a qualified gem laboratory can identify treatments. Reputable dealers disclose treatments; buyers should ask specifically and get guarantees in writing.
Market Value
Jadeite commands extraordinary prices:
Record prices for jadeite jewelry regularly exceed millions of dollars. A jadeite bead necklace sold for $27.4 million in 2014; a jadeite bangle achieved $7.4 million in 2017.
Quality factors determine price. Color (particularly imperial green), translucency, texture, size, and craftsmanship all affect value. A small piece of fine imperial green jadeite may be worth more than a large piece of lesser material.
Investment potential has attracted collectors. Fine jadeite has appreciated significantly over recent decades, though the market can be volatile.
Counterfeiting is common due to high values. Glass, plastic, and dyed stones may be sold as jadeite. Expert evaluation is essential for major purchases.
Contemporary Significance
Jadeite remains central to Chinese jewelry culture:
Cultural symbolism associates jadeite with good fortune, health, and protection. Many Chinese wear jadeite daily as talismans.
Gifting traditions make jadeite jewelry important for weddings, births, and other life events. A jadeite bangle may be given to a daughter or daughter-in-law as a family treasure.
Fashion integration has brought jadeite to international attention. Contemporary designers create jadeite jewelry that appeals to global tastes while maintaining cultural significance.
Sustainability concerns have emerged regarding jadeite mining. Environmental damage and human rights issues in Burma have led some consumers to seek ethically sourced alternatives.
Conclusion
Jadeite represents a remarkable chapter in the history of jade. Introduced to China only three centuries ago, it has become the most precious jade variety, commanding prices that reflect its beauty, rarity, and cultural significance. The vivid colors and high translucency of fine jadeite offer aesthetic qualities distinct from traditional nephrite.
For collectors and enthusiasts, jadeite presents both opportunities and challenges. The market is complex, with treatments, forgeries, and ethical concerns to navigate. But genuine fine jadeite offers beauty and value that justify the effort required to acquire it knowledgeably.
Whether worn as jewelry, collected as art, or treasured as cultural heritage, jadeite continues the ancient Chinese appreciation for jade while bringing new qualities to this enduring tradition. In its brilliant colors and crystalline depths, jadeite represents nature's artistry enhanced by human skill—a combination that has captivated connoisseurs for centuries and will continue to do so for generations to come.
