Jadeite is one of the gem materials known as jade. It is admired for its toughness, smooth polish, wide range of colors, and long history in jewelry and decorative art. Green jadeite is the most familiar, but the material can also be white, lavender, yellow, orange, gray, black, brown, or nearly colorless.
This guide explains what jadeite is, how it differs from nephrite, which features influence appearance and value, and why treatment disclosure matters.
Jadeite and nephrite: two kinds of jade
The word “jade” does not name a single mineral. In gemology, it most commonly includes jadeite and nephrite. Jadeite is a pyroxene mineral, while nephrite is an aggregate of amphibole minerals. Their chemistry differs, but both have interlocking structures that make them exceptionally tough.
Toughness is resistance to breaking or chipping; hardness is resistance to scratching. Jadeite measures about 6.5 to 7 on the Mohs hardness scale. That makes it suitable for jewelry, but it is not immune to scratches or sharp impacts.
Where jadeite forms
Jadeite forms under high-pressure geological conditions associated with tectonic zones. Important sources include Myanmar and Guatemala, with occurrences also documented in Japan, Russia, Kazakhstan, and other locations. Origin cannot be confirmed reliably from color or appearance alone because material from different locations can overlap visually.
The many colors of jadeite
Jadeite’s color is one reason the gem is so versatile. Green is traditionally the best-known and often the most highly valued color. The trade term “Imperial jade” is reserved for exceptional jadeite with vivid green color, fine texture, and strong translucency. It should not be used as a general label for every bright green stone.
Lavender, white, black, yellow, orange, and colorless jadeite can also be beautiful and desirable. Uneven color is common, and skilled cutters may position patches, veins, or contrasting areas as part of a carving or jewelry design.
How jadeite quality is evaluated
Gemological evaluation looks at several connected factors:
- Color: Hue, saturation, tone, and distribution strongly influence appearance.
- Transparency: Jadeite ranges from opaque to semi-transparent. Light entering the stone can create a luminous effect.
- Texture: Fine, tightly intergrown crystals generally support a smoother polish and finer visual texture.
- Clarity and condition: Fractures can reduce durability. Other inclusions may be neutral, distracting, or visually interesting depending on the piece.
- Cut and craftsmanship: Shape, thickness, symmetry, polish, and carving quality all matter.
- Treatment: Dye, bleaching, polymer impregnation, wax, heat, and coatings can change appearance or durability and should be disclosed.
Color and clarity are not enough to identify jadeite or determine whether it has been treated. Professional gemological testing may use microscopy, spectroscopy, and other instruments that cannot be replaced by a home test.
What do A, B, and C jade mean?
In the jade trade, “A jade” generally refers to natural jadeite without dye or polymer impregnation; a traditional surface waxing may be accepted within that description. “B jade” commonly refers to material that has been chemically bleached and impregnated with polymer. “C jade” is dyed, and “B+C” combines impregnation and dye.
These labels describe treatment categories, not an automatic grade of beauty or craftsmanship. If treatment status is important, look for a report from a qualified gemological laboratory and read exactly what the report identifies.

Jadeite in Chinese history
Jade has been important in Chinese culture for thousands of years, but much of the jade used in ancient China was nephrite. Jadeite from Myanmar became widely worked and especially prominent in China during the eighteenth century and the Qing dynasty. Keeping that distinction clear avoids applying the full history of ancient Chinese nephrite directly to jadeite.
Across periods and regions, jade has been associated with beauty, virtue, status, protection, and continuity. These meanings are culturally significant, but they are symbolic rather than measurable guarantees.
How to choose jadeite jewelry
Start with the qualities you can evaluate: design, dimensions, stated material, treatment disclosure, setting, and how the piece will be worn. Natural variation is expected, so compare product photos carefully and ask questions when a feature is essential to your decision.
