Yellow Jade (Nephrite or Quartzite)

Physical Properties

Hardness: 6-7 (Mohs scale); Color: Pale yellow to honey gold; Luster: Waxy to vitreous; Crystal Structure: Monoclinic (fibrous) for nephrite or Trigonal for quartzite; Specific Gravity: 2.6-3.0.

Formation & Geological History

Usually formed through low-grade metamorphism of ultrabasic rocks or dolomitic limestones. This specific piece appears to be a river-tumbled pebble, polished by water transport over centuries.

Uses & Applications

Used primarily for jewelry (cabochons), ornamental carvings, stone decor, and as 'worry stones' in holistic practices.

Geological Facts

Yellow jade is often associated with wisdom, joy, and fire energy in various cultural traditions. True yellow nephrite is rare; much of the yellow 'jade' in the market is actually high-quality yellow quartzite.

Field Identification & Locations

Identify in the field by its waxy surface, lack of visible crystals, and extreme toughness (resistance to fracturing). Found often in alluvial deposits and river beds in regions like Myanmar, China, and British Columbia.
