What is Heliotrope Stone?
Heliotrope is a variety of chalcedony, a cryptocrystalline form of silica. Its distinctive appearance features a deep green base with bright red spots caused by iron oxide inclusions. This unique combination has earned it the evocative nickname "bloodstone" and has made it a prized material in both jewelry and decorative arts throughout history.
Etymology and Historical Significance
The name "heliotrope" comes from the ancient Greek words "helios" (sun) and "trepein" (to turn). Ancient Greeks believed that when placed in water, the stone would turn the sun's reflection blood-red. The first historical mentions of heliotrope date back to Natural History by Pliny the Elder in the 1st century AD, where he described its use in ancient Egyptian and Babylonian cultures.

Formation and Natural Occurrence
Heliotrope forms through hydrothermal processes, where silica-rich solutions fill cavities in rocks. The distinctive red spots develop from iron oxide inclusions during crystallization. The stone typically occurs in massive form rather than as individual crystals.
Global Deposits and Mining
Major Deposits
- India (particularly in Kathiawar)
- Brazil (Mato Grosso)
- Australia (Western Australia)
- United States (California, Nevada)
- China (Xinjiang region)
- Madagascar
- Germany (Saxony)
Mining Process
Heliotrope is typically extracted through open-pit mining operations. Miners carefully remove the surrounding rock to expose veins of the material. The stone is then extracted in blocks or chunks, which are later cut and processed for various applications.
Production and Market Value
While exact global production figures are not publicly available, the gemstone industry estimates annual heliotrope production at several thousand tons. Raw material prices vary significantly based on quality, with high-grade specimens commanding $50-200 per kilogram. However, these figures fluctuate based on market conditions and source location.
