Jadeite Jade

Imperial jadeite is the world's most expensive gem material by weight at auction, single bangles have passed US$25 million.

Jadeite Jade is inosilicate (pyroxene), NaAlSi₂O₆. In the hand, it rates 6.5 to 7 on the Mohs scale, and it runs emerald 'imperial' green and apple green.

What it is

The geology.

Jadeite Jade carries the formula NaAlSi₂O₆. It belongs to the monoclinic (granular aggregate) system. Its listing category is inosilicate (pyroxene).

It sits at 6.5 to 7 on the Mohs scale. The surface reads greasy to vitreous; takes glassy polish. Light behaviour is translucent to opaque. Specific gravity runs 3.30 to 3.38. The streak is white. It breaks with splintery; extremely tough interlocking texture.

The denser, glassier jade, granular-sparkly texture under a loupe, icy heft, ringing chime when tapped, polishing to a sharper gloss than nephrite's oily sheen.

It turns up mostly as bangles, cabochons, carvings or boulders with weathered rind.

Where it comes from

The origins.

Myanmar (Kachin, the world's gem source), Guatemala (Motagua Valley), Japan, California (USA).

On value, the database notes: from affordable utility grades to record-shattering imperial green.

What people work with it for

Traditional associations.

In energy work traditions, associated with harmony, prosperity, and protective good fortune.

This is lore, and we label it as lore. The measurable facts are further up the page.

What to look for

Spotting the real thing.

The denser, glassier jade, granular-sparkly texture under a loupe, icy heft, ringing chime when tapped, polishing to a sharper gloss than nephrite's oily sheen.

The most treatment-ridden gem on Earth: polymer-impregnated and dyed 'B/C jade' saturates tourist markets, untreated 'Type A' certification is the standard.

Looks like How to tell them apart
Nephrite jade Nephrite is fibrous-silky, slightly lighter, with an oilier polish, both are true jade
Dyed/polymer 'B/C' jadeite Treated jadeite shows acid-etch spiderweb under magnification and dye in fractures
Serpentine and dyed quartzite Serpentine is knife-soft; quartzite shows granular sparkle with boundary dye
Check it yourself

At-home tests.

A loupe and a window seat settle most questions about jadeite jade. No workshop required.

Test What you should see
Heft noticeably dense (SG 3.3+)
Chime test on bangles long bright ring
Loupe fine granular (not fibrous) interlocked texture
By eye No dye in fractures

Anything that scratches, burns or dissolves the piece is a lab job. Get it appraised rather than testing it apart.

How to live with it

Care & handling.

At 6.5 to 7 on the Mohs scale it handles careful wear but scratches against quartz and dust. Store it separately and take rings off before rough work.

It breaks with splintery; extremely tough interlocking texture, which is worth knowing before you set it or drop it.

Warm water and a soft cloth clean almost everything. Ultrasonic tanks, steamers and household cleaners are where pieces get ruined.
