An intense green characteristic of beautiful tsavorites
This piece immediately stands out for its strong chromatic presence. Its green naturally varies across different zones of the crystal, from fresh, bright tones to areas of much deeper, saturated green.
Light penetrates the most translucent areas before meeting the numerous internal crystalline surfaces. The result is a multitude of green, white and silvery reflections that give the specimen remarkable visual depth.
This complex rough structure is especially interesting for the collector: unlike a cut gem, it preserves natural characteristics acquired during its growth and allows direct observation of part of its geological history.

Tsavorite: one of the great collection garnets
Tsavorite is the green variety of grossular garnet, whose coloration is mainly related to the presence of vanadium and chromium.
It holds a special place in the world of gems: the finest tsavorites can offer extremely vivid green without requiring treatments commonly used for some other precious stones.
Natural crystals combining beautiful color, interesting transparency and substantial weight are particularly appreciated, especially since tsavorite is often found in crystals of modest dimensions.
With its 5.10 carats, this specimen thus has a particularly appealing presence for a collection of rough gems.

A relatively recent discovery
The history of tsavorite is fascinating since it only joined the international market for gemstones in the second half of the 20th century.
Geologist and prospector Campbell Bridges discovered exceptional green grossular garnets in Tanzania in the late 1960s. Significant occurrences would later be found in Kenya.
In the early 1970s, this gem was named “tsavorite,” inspired by the Tsavo region in East Africa.
In just a few decades, it advanced from an almost unknown geological curiosity to one of the most prestigious green garnets on the gem market.

Geology that explains its rarity
Tsavorite is rare because its formation requires a very particular combination of geological and chemical conditions. Mineable occurrences are concentrated mainly in a part of East Africa, notably Kenya and Tanzania.
Extraction can be difficult and the production of high-quality material remains irregular. Crystals are often heavily fractured by the substantial geological stresses experienced during their formation.
Finding specimens that simultaneously offer attractive color, translucent zones, a strong presence and several carats of natural material therefore becomes particularly interesting for the collector.

A 5.10-carat collectible piece
This tsavorite displays a particularly marked mineralogical character. Its irregular morphology, multiple growth surfaces and internal structures form a complex crystalline landscape that becomes spectacular under close observation.
Its dimensions of 11.4 × 8.6 × 6.5 mm also allow full enjoyment of its volume and color variations.
This is not simply gem material intended to be cut: its rough state is precisely part of its appeal, as it preserves the natural appearance in which this gem developed in the depths of East Africa.

A very beautiful opportunity to acquire a Tanzanian tsavorite of 5.10 carats, 100% natural, combining intense green, ample volume and remarkable crystal character, ideal to enrich a collection dedicated to rare gems and great minerals of Africa.
