Nephrite Jade: The Older Stone, Explained
Nephrite Jade: The Older Stone, Explained
What nephrite is
Nephrite is a calcium magnesium silicate, softer and tougher than jadeite. Its structure is fibrous, which is why it resists breaking: a nephrite bangle can survive a knock that would crack jadeite. Colours run from cream and yellow-green to deep spinach green and near-black.
Why Chinese jade history is mostly nephrite
Chinese jade working began with nephrite, long before jadeite reached China from Myanmar in quantity during the Qing dynasty. The classical jade objects, cong tubes, bi discs, burial suits and carved pendants, are almost all nephrite. When Chinese texts praise jade for virtue, they are usually describing nephrite.
That history is why nephrite is sometimes called "the old jade" in the trade. It is not a lesser stone; it is a different one, worked for far longer.
Jadeite versus nephrite
- Hardness. Jadeite is harder on the Mohs scale; nephrite is tougher.
- Look. Jadeite is usually more translucent and glassy. Nephrite is more opaque and waxy.
- Price. Fine imperial jadeite is far more expensive. Good nephrite is affordable and often better value for everyday wear.
- Treatment. Nephrite is less commonly bleached or polymer-treated than jadeite, though waxing is normal.
Looking at a nephrite bangle
- Evenness. Fine nephrite has a consistent, slightly oily lustre. Patchy dull spots can indicate surface wax or low-grade material.
- Sound. Tap gently with a fingernail. A clear ring suggests no internal cracks; a dull thud is a reason to look closer.
- Size. Bangle fit is measured by inner diameter. Too small will not pass the knuckles; too large will slide and chip.
Care
Wear it. Nephrite benefits from the skin's natural oils and looks dull when stored for long periods. Avoid household cleaners, chlorine and hard knocks. Store separately from harder stones such as quartz, which can scratch it.
Common questions
Is nephrite real jade?
Yes. Jade is a category that includes both nephrite and jadeite; both are legitimate jade.
Why is my bangle cloudy?
Most nephrite is semi-opaque. Perfectly clear nephrite is rare and expensive; heavy cloudiness is normal and not a fault.
Can it be resized?
No. A bangle is cut as a continuous ring. Fit must be right at purchase.
