Physical properties

Formation & geological history

Formed through the deposition of silica from groundwater in the cavities of igneous rocks or sedimentary formations. While 'Yellow Jade' is a trade name, it is geologically a form of chalcedony or quartzite rather than nephrite or jadeite.

Uses & applications

Primarily used for decorative jewelry, beads, cabochons, and small carvings. It is popular in the metaphysical community as a 'joy stone.'

Geological facts

In the gemstone trade, the term 'Jade' is often applied to various yellow stones like calcite, serpentine, or quartz to increase marketability. True yellow nephrite exists but is extremely rare.

Field identification & locations

Identify by its hardness (it cannot be scratched by a steel knife) and its translucent to opaque appearance. It lacks the internal 'fibrous' weave of true nephrite jade. Commonly sourced from Brazil, Uruguay, and Madagascar.
