Gemstone profile and identification guide

Jadeite

Part of the identity of Jadeite comes from the producing regions associated with it. That combination of green body colour, 6.5 Mohs hardness, and silky lustre is what usually makes it recognisable in practice. The secondary white note often matters more than people expect when separating it from lookalikes.

Overview

Part of the identity of Jadeite comes from the producing regions associated with it. That combination of green body colour, 6.5 Mohs hardness, and silky lustre is what usually makes it recognisable in practice. The secondary white note often matters more than people expect when separating it from lookalikes.

Did you know? Jadeite is commonly associated with material from Myanmar, though the broader trade may draw on multiple localities.

Identification

Name: Jadeite

Scientific classification: Pyroxene (Jadeite)

Hardness: 6.75 Mohs

Transparency: translucent to opaque

Lustre: vitreous to greasy

Crystal system: Monoclinic

Primary colour: Green

Secondary colour: White

Colour family: Greens

A practical identification pass begins with the visible basics: translucent transparency, silky lustre, 6.5 Mohs hardness, and a monoclinic / orthorhombic crystal system. The interaction between green and white tones is more useful than the primary colour alone when comparing candidates. Useful side-by-side comparisons include Topaz, Moonstone, Peridot.

Chemical formula: Sodium aluminum silicate (NaAlSi2O6)

Mohs hardness: 6.75

Crystal system: Monoclinic

Lustre: vitreous to greasy

Transparency: translucent to opaque

Streak: White

Cleavage: Generally obscured by aggregate texture

Fracture: Splintery to uneven

Specific gravity: 2.90-3.38 (species-dependent)

Refractive index: 1.60-1.68 (species-dependent)

Optical phenomena: None commonly reported

Colour range: Green, White

Common inclusions: Fibrous/granular textures, black mineral spots, and healed fractures

Geological environment: Jadeite occurs in High-pressure metamorphic terrains and serpentinized ultramafic environments. Its Monoclinic structure reflects the pressure-temperature conditions of those host rocks, with notable occurrences in Myanmar (Hpakan), Guatemala (Motagua Valley), Japan, Kazakhstan.

Principal mining regions: Myanmar (Hpakan), Guatemala (Motagua Valley), Japan, Kazakhstan

Important commercial sources: Myanmar is the dominant commercial source of gem-quality jadeite; Guatemala is the key secondary source

Historical significance: Jade has exceptional cultural significance across East Asian and Mesoamerican traditions.

Common treatments: Bleaching, polymer impregnation, and dyeing are established trade treatments and require disclosure.

Synthetic or imitation forms: Dyed quartzite, serpentine, glass, and composite imitations are common.

Common look-alikes: topaz, moonstone, peridot

Jewellery uses: Jadeite is used chiefly for A good fit for collectors and jewellers looking for visible character without needing the highest hardness category.. In the trade it is commonly fashioned as faceted stones, calibrated cuts, and higher-clarity collector pieces, with Mohs hardness 6.75 guiding suitable jewellery applications.

Care recommendations: Jadeite should be cleaned with lukewarm water, mild soap, and a soft brush. At Mohs 6.75 in the Monoclinic system, avoid steam cleaners, harsh chemicals, and high-impact wear. Protect cleavage directions from sharp knocks during wear and setting.
