Cinnamon Stone

Cinnamon Stone is the popular name for hessonite, a brownish-orange to honey-colored variety of grossular garnet. Its warm, spicy color, caused by iron and manganese, recalls ground cinnamon, giving the stone its trade name.

Hessonite has a slightly lower refractive index and density than many garnets, and it characteristically contains swirly, treacle-like inclusions that produce a distinctive 'heat-haze' or 'scotch-in-water' internal appearance. This texture is so typical that it is almost a fingerprint of the stone.

In Vedic astrology, hessonite is known as Gomed and is one of the nine sacred Navaratna gemstones, which keeps it in steady demand.

Cinnamon stone forms in metamorphosed calcium-rich rocks, skarns, and serpentinites, where impure limestones recrystallize under heat and pressure and grossular garnet crystallizes with traces of iron and manganese.

Sri Lanka is the classic and most famous source, especially for fine astrological-grade gomed; additional deposits occur in India, Brazil, Madagascar, Tanzania, and Canada. The durable garnets often weather out of their host rocks and concentrate in alluvial gem gravels, where much of the Sri Lankan material is recovered by traditional pit and river mining.

Look for a warm cinnamon-brown to honey-orange color, glassy to slightly resinous luster, single refraction, and a hardness near 6.5-7. The streak is white.

The most diagnostic feature is the internal swirly, roiled texture (like syrup stirred into water), often with rounded crystal inclusions. This, plus single refraction and the absence of cleavage, confirms hessonite.

Look-alikes include spessartine (more pure orange), citrine (doubly refractive, softer), and topaz (doubly refractive). The treacly inclusions and garnet refractive index distinguish cinnamon stone from these.

Cinnamon stone is used chiefly in jewelry and astrology. It is faceted into rings, pendants, and beads as an affordable warm-toned gem. In Vedic astrology it is the gomed gemstone, worn as one of the Navaratna stones and associated with the lunar node Rahu, which drives much of its market.

Its hardness makes it suitable for most jewelry with reasonable care.

Metaphysically and astrologically, hessonite is linked to focus, stability, and dispelling negativity, though these claims are not scientific. Its appeal lies in warm color, affordability, and cultural significance.
