What is spessartine?

Spessartine (also spelled spessartite) is the species of the garnet group rich in manganese: Mn3Al2(SiO4)3. It is manganese that gives it shades from yellow-orange to vivid orange or reddish orange. Like other garnets, it crystallises in the cubic system and has no cleavage. Its hardness is 6.5 to 7.5 (gem-quality stones lie more towards 7 to 7.5) and its density is about 4.1 to 4.3. The name comes from the Spessart, an upland region of Bavaria in Germany, where it was described.

Beware of a homonym: in petrology, spessartite is also the name of a volcanic rock, named after the same region, which has nothing to do with garnet. On this page, we always mean the mineral.

Spessartine is rarely pure: it forms series with almandine (iron) and other garnets, and the colour depends on the mixture. The more iron, the redder or browner the tint. It is found in pegmatites (see pegmatites), in metamorphic rocks and in some volcanic rocks.

Mandarin garnet

Mandarin garnet is a trade name for a spessartine of a very vivid orange, comparable to that of the mandarin orange. It was discovered in 1991 (one source gives 1992) near the Kunene River, in north-western Namibia, on the border with Angola. The small Namibian mines closed at the end of the 1990s. Most gem spessartine now comes from Nigeria and Tanzania, with Madagascar and Mozambique also supplying it.

Authors do not agree on how the name should be used: some reserve it for Namibian stones, others extend it to all spessartines of a brilliant orange, whatever their origin. A “mandarin” label therefore mainly describes a colour, not a precise place, unless stated otherwise.

Traditional symbolism

The orange of spessartine evokes fire, sunset and creativity. Modern books on crystals associate it with creativity, enthusiasm, vitality and sociability, often through the sacral chakra. None of these associations is old: spessartine was only described in the 19th century, and mandarin garnet is a commercial product of the 1990s.

These are therefore modern conventions. No study shows any effect of the stone on creativity or mood. Its orange can be a pleasant visual cue during a writing or drawing exercise.

How to use it

As jewellery: its hardness of 7 to 7.5 suits a ring, with care against knocks. Small faceted stones are common (see our guide to gemstone jewellery).
As a pocket stone: a small pebble or a rough crystal.
As a creativity aid: place an orange stone on your work table before writing, drawing or planning. It serves as a reference point, nothing more.
As a collector’s piece: well-formed crystals (Amelia in Virginia, Latinka in Bulgaria, Namibia) are sought after by collectors.

Care and cleansing

Cleaning: lukewarm water and mild soap, soft brush. Dry it.
Sun: no effect on the colour.
Knocks: stones are hard but brittle; keep them away from hard surfaces.
Ultrasonic and steam cleaning: possible for stones without fissures; avoid them if in doubt.
Symbolic cleansing: smoke, sound, moonlight (guide).

Recognising a genuine spessartine

Sign	Natural spessartine	Imitation or confusion
Colour	vivid orange, sometimes tinged with red or brown	very uniform orange: glass; citrine or heat-treated topaz that is more yellow
Interior	small crystal inclusions, veils	round bubbles: glass
Weight	heavy (density 4.1 to 4.3)	light: glass or plastic
Double image	none (singly refractive garnet)	doubled images: tourmaline, zircon, topaz

Spessartines are also confused with hessonite (orange-brown grossular garnet), citrine in orange shades, or orange calcite. Treatments are rare on this stone. See real or fake stone and our commitments.

How to choose

A quality spessartine garnet is a clear orange, translucent, with few visible inclusions. Fine stones over two carats are rare and expensive; small stones and rough crystals are more affordable. The bright glow of a “mandarin” is what enthusiasts look for. Be aware that a label may say “mandarin” for a simple orange stone: ask about origin and any treatments.

Pairings: with almandine to compare red and orange, or with hessonite or citrine for a warm ensemble. Also read our guide.

Frequently asked questions

What is the difference between spessartite and spessartine?

None for the mineral: spessartine is the international mineralogical spelling, spessartite the traditional French one. In petrology, spessartite also designates a volcanic rock.

Is mandarin garnet a spessartine?

Yes. “Mandarin” is a trade name for a spessartine of a very vivid orange, discovered in Namibia in 1991.

Why is spessartine orange?

Because of the manganese in its composition, combined with a little iron depending on the stone. The more iron, the more the colour leans towards red.

Can spessartine be worn in a ring?

Yes, with care: its hardness of 7 to 7.5 is suitable, but knocks can damage it.

Is spessartine rare?

Fine stones of an intense orange are fairly rare, especially over two carats. Small stones and rough crystals are common.
