Complete Guide to Jade Types: Jadeite vs Nephrite, Colors, and Quality

Understanding jade types is essential for making informed purchases. This guide covers everything from jadeite vs. nephrite to the most prized jade colors and quality grading.

Jadeite vs. Nephrite: What's the Difference?

Despite sharing the name "jade," these two minerals are quite different:

Jadeite

• Hardness: 6.5-7 on Mohs scale
• Structure: Interlocking crystal grains
• Luster: Vitreous to greasy
• Primary Source: Myanmar (Burma)
• Value: Generally higher, especially gem-quality pieces
• Transparency: Can be highly translucent

Nephrite

• Hardness: 6-6.5 on Mohs scale
• Structure: Fibrous crystals woven together
• Luster: Waxy to greasy
• Primary Sources: Canada, China, Russia, New Zealand
• Value: Generally lower than jadeite
• Toughness: Extremely durable (great for carvings)

Jadeite Jade Grades: A to C

Type A Jade (Natural)

100% natural jadeite with no chemical treatment. May have been waxed or oiled for surface luster only. Type A jade retains its natural color and structure. This is the highest quality and most valuable grade.

Type B Jade (Bleached and Polymer Impregnated)

Jade that has been bleached to remove impurities, then injected with polymer for transparency. While still real jade, it will yellow and deteriorate over time. Not recommended for investment.

Type C Jade (Dyed)

Jade that has been dyed to enhance or change its color. These colors will fade over time, especially with exposure to light and heat. Type C jade has minimal long-term value.

Type B+C Jade

Jade that has been both bleached and dyed. The poorest quality option, with colors that fade quickly and structure that will deteriorate.

The Most Valuable Jade Colors

Imperial Green ()

The most valuable jade color—vivid, translucent emerald green with no visible color zoning. Imperial jade commands the highest prices in the world.

Lavender/Purple Jade ()

Highly prized translucent lavender jade. Ranges from light lavender to deep purple. Particularly popular in modern jewelry designs.

White Jade ()

Prized for its milky white appearance with subtle green undertones. Represents purity and is associated with the goddess Guanyin.

Black Jade ()

Solid black jade with high luster. Often has subtle green or gray undertones when held to light. Popular in men's jewelry.

Ice Jade ()

Highly translucent jade with icy clarity. The internal structure scatters light beautifully, creating a glowing effect. Increasingly popular in contemporary designs.

Yellow Jade ()

Ranges from pale yellow to deep honey gold. Associated with earth energy and often used for prosperity charms.

2. Clarity

Examine for:

3. Cut/Transparency

Quality jade should be:
• Translucent to semi-transparent
• Evenly cut with smooth surfaces
• Well-polished with good luster

For carved pieces:
• Detail and precision of carving
• Symmetry and balance
