Tsavorite is the vivid green grossular garnet from East Africa. Brilliant, untreated and rare in large sizes, it is a prized alternative to emerald.
Tsavorite is graded chiefly on the intensity and purity of its green; the most vivid, slightly bluish greens top the market.
An intense, pure-to-bluish green with high brilliance — the most coveted and valuable grade.
Lively green stones seen in most jewelry; excellent value with great sparkle.
Paler or more yellowish stones — attractive and more budget-friendly.
Six main criteria determine the price per carat. It is their combination that sets the final value.
The decisive factor: an intense, pure green (slightly bluish) is most valuable; too light or too yellowish reduces value.
Kenya and Tanzania (the Tsavo region) are the classic sources; Madagascar also produces fine stones.
A key advantage: tsavorite is essentially never treated, so its vivid color is fully natural.
Eye-clean stones command a premium; the cut should maximize brilliance and color while keeping good proportions.
Tsavorite rarely forms large clean crystals, so stones above 2–3 ct are scarce and rise sharply in price per carat.
A report from a recognized lab (GIA, SSEF, Gübelin, GRS, AGL) confirms identity, origin and treatment, securing the valuation and resale.
The most valuable tsavorite is an intense, slightly bluish green with strong brilliance and life.
Its high dispersion and brightness make fine stones especially lively, rivaling emerald without treatment.
Unlike emerald, tsavorite is untreated and cleaner, making it a durable, honest green choice.
But it rarely grows large, so big fine tsavorites are genuinely rare and command steep premiums.
Geographic origin can be a strong prestige marker that weighs on value.
