Geological facts

Jadeite is one of the two distinct minerals recognized as jade (the other being nephrite). Historically, fine translucent imperial jadeite has fetched extremely high prices at international auctions.

Field identification & locations

Identified by its dense, fibrous interlocking crystal structure, high specific gravity (feels heavy for its size), and vitreous luster when polished. Commonly sourced from Myanmar (Burma), Guatemala, and Russia.
