Jadeite is a dense, tough pyroxene mineral that forms the most prized variety of jade. Collectors often identify it by its waxy to vitreous luster and characteristic granular or fibrous texture, frequently found in metamorphic subduction zone environments.

Spotting jadeite in the field

Field marks
  • 1

    Green, lavender, white or orange, with a slightly granular sugary texture under magnification

  • 2

    Very tough and harder than nephrite at 6.5 to 7

  • 3

    Higher density than nephrite, noticeably heavy in the hand

Jadeite is the rarer and more valuable of the two true jades, forming only in high-pressure low-temperature subduction settings, which is why it comes from so few places on Earth. Myanmar dominates the gem trade, with Guatemala the other significant source. In the United States, San Benito County in California has the notable occurrence. The sugary granular texture under a loupe separates it from nephrite's fibrous felt.

Straight answers

Is it worth cutting?
Tough and slow to work, and it takes an exceptional polish. Imperial jadeite is usually cut to preserve weight rather than to a standard shape.
What is it really worth?
Fine imperial green jadeite is among the most valuable gem materials in the world. Treatment is rampant: bleached and polymer-impregnated jadeite is called B jade and dyed material is C jade, and both must be disclosed.
Can you legally keep it?
Myanmar jadeite is subject to trade restrictions and is tied to serious human rights concerns, so provenance genuinely matters here. Guatemalan material is a cleaner alternative.

Field-hunting tip

Look in metamorphic rocks like serpentinite or blueschist country, the host setting where jadeite typically forms. If you start seeing albite, glaucophane, lawsonite in float, you are in the right ground. Field specimens usually show a massive, granular, or compact fibrous habit, so train your eye for that shape before scanning the outcrop. In the U.S., the densest reported localities are in California, Washington. Start trip planning there.
