What is tsavorite?

Tsavorite is a green variety of grossular garnet (Ca3Al2(SiO4)3), a calcium-aluminium silicate of the garnet group. Its colour comes from small amounts of vanadium and/or chromium, the same elements that colour some emeralds. It is cubic, without cleavage, hard (7 to 7.5) and brilliant, with a density of 3.6 to 3.7.

It is a recent stone in the history of gems. The geologist Campbell Bridges found a first deposit in 1967 in northern Tanzania, then one in 1971 in Kenya, near the Tsavo region. The name “tsavorite” was proposed by Henry Platt, president of the jewellery house Tiffany & Co., who launched the stone on the American market around 1974. It is therefore a trade name that became common, not an ancient name.

Tsavorite is rare: the crystals are small, and fine stones over two carats are uncommon. Some is also mined in Madagascar. It differs from emerald in its higher hardness, its vivid lustre and the fact that it is very seldom included.

Do not confuse it with other “green garnets”

Name	What it is
Tsavorite	green grossular, transparent, coloured by vanadium and/or chromium, faceted stone
Hydrogrossular (“Transvaal jade”, “African jade”)	massive grossular, opaque or translucent, green, from South Africa; sold as cabochon or pebble, it is a different material
Demantoid	another species (andradite), vivid green or yellow, very strong dispersion
Uvarovite	another species, emerald green, in small crystals in a druse

A cut tsavorite is never found as a pebble or as beads: if a “tsavorite” label refers to a large opaque bead or a green pebble, it is probably another material.

Traditional symbolism

Its deep green has led modern crystal books to associate it with growth, renewal, prosperity and balance of the heart. It is sometimes presented as the “emerald of East Africa”.

These ideas are modern conventions (the stone has only been known under this name for a few decades). No study shows any effect of the stone on luck, money or health. Its value lies mainly in its beauty and rarity.

How to use it

As jewellery: ring, earrings, pendant. Its hardness (7 to 7.5) allows regular wear, with the usual care against knocks (see our guide).
As a collector’s stone: a well-kept cut stone in a case.
As a gift: to mark a birthday or a renewal (a birth, a new start).
In meditation: observe the brilliance of a faceted stone in daylight, its reflections. A simple exercise: follow one reflection without hurry, then note what it brings to mind.

Care and cleansing

Cleaning: lukewarm water, mild soap, soft brush; dry with a cloth.
Sun: no risk; the colour is stable.
Knocks: the stone is hard but can chip on its edges.
Ultrasonic cleaning: generally possible for a clean stone, but avoid it if there are fissures.
Symbolic cleansing: smoke, sound, moonlight (guide).

Recognising a genuine tsavorite

Sign	Natural tsavorite	Imitation or confusion
Brilliance	very vivid, vitreous to almost adamantine	dull: glass; too bright: zircon or synthetic garnet
Interior	clean; sometimes fine needle inclusions	round bubbles: glass
Double image	none (singly refractive)	doubled images: green tourmaline, peridot
Size	small stones, often under 2 carats	large, very cheap, vivid green stone: glass or laboratory garnet

Synthetic green garnets (yttrium-aluminium garnet, known as YAG) imitate tsavorite and demantoid in the trade; gemmological tests tell them apart. An expensive tsavorite should be bought with a laboratory certificate. See real or fake stone and our commitments.

How to choose

The value of a tsavorite depends first on its colour (an intense green, neither too dark nor too pale), then on its clarity and size. Fine stones are relatively expensive, especially above two carats; small stones are more affordable. Be wary of promises of “tsavorite” in large beads or pebbles: look instead for a cut stone with its origin stated (Tanzania, Kenya).

For a more affordable green alternative, see peridot or green aventurine. Pairings: with orange spessartine garnet for a set of coloured garnets. See also the guide.
