Synopsis

Discover the complete story of hessonite garnet, the mysterious orange gemstone known throughout history as the Cinnamon Stone, Gomed, and the sacred gemstone of Rahu.

In this comprehensive hessonite gemstone guide, veteran gemstone specialist Hans J Steinberg draws on forty years of experience to explore every major aspect of this fascinating variety of grossular garnet. Combining practical gemology, geological science, history, jewelry, collecting, valuation, and cultural tradition, this book provides an in-depth reference for collectors, jewelers, gemologists, students, investors, and anyone wondering: What is a hessonite garnet?

Hessonite is instantly recognizable for its warm honey, amber, reddish-orange, and cinnamon-brown colors. Yet behind its distinctive appearance lies a gemstone with an unusually complex history. It has traveled through ancient Indian Ocean trade routes, appeared in Roman and European jewelry, entered royal and aristocratic collections, and acquired a major religious and astrological role in South Asia.

This book examines the gemstone from its formation deep within the Earth to its place in the modern international gemstone market.

Inside, you will learn about:

• The difference between hessonite, grossular garnet, spessartine, zircon, citrine, topaz, sapphire, spinel, and glass
• The geology and mineral composition of natural hessonite
• The physical and optical properties of grossular garnet
• Hessonite colors, including cinnamon, honey-orange, amber, golden-orange, and reddish-orange
• The famous treacle effect, oily appearance, and heat-wave-like internal structure
• Natural hessonite inclusions and microscopic identification features
• How gemologists identify genuine hessonite using magnification, refractive index, specific gravity, spectroscopy, and laboratory testing
• How to distinguish natural hessonite from synthetic garnets, imitations, coatings, fillings, glass, and composite stones
• The major hessonite mining regions of Sri Lanka, Tanzania, Madagascar, India, Pakistan, Kenya, Brazil, Canada, Namibia, Australia, Russia, and the United States
• Why Sri Lankan Ceylon hessonite remains historically important
• How origin, color, clarity, cut, transparency, size, and certification influence value
• Ancient hessonite history and the origin of the name Cinnamon Stone
• Hessonite in Roman jewelry, medieval Europe, royal collections, museums, and international auctions
• The role of Gomed in Hindu tradition and Vedic astrology
• Hessonite’s association with Rahu and the Navaratna gemstones
• Buddhist traditions, European folklore, mythology, and ancient gemstone beliefs
• How to buy, collect, evaluate, certify, store, and understand hessonite gemstones

Unlike brief crystal guides or astrological summaries, this book treats hessonite as both a scientifically important mineral and a historically significant gemstone. It explains why some stones appear bright and fiery while others possess a soft, syrupy interior; why hessonite is frequently mistaken for orange zircon or spessartine garnet; and why laboratory identification becomes important for valuable, unusually large, or historically significant specimens.
