非凡的大 TSAVORITE 晶体 • 5.40 克拉 • 非常罕见的强烈绿色祖母绿饱和度 - 高度: 15 mm - 宽度: 9 mm- 1.08 g - (1)

DESCRIPTION:
Light catches a ridge, slips through a transparent window and gathers in a pocket of vivid Emerald Green. This tsavorite from Tsavo, Kenya reveals its character through these successive encounters: brilliant surface reflections, luminous internal passages and richly textured contours that give the specimen a distinctly sculptural presence.

Emerald Green defines the piece throughout. In thicker areas, it acquires greater depth and concentration; along thinner edges and more transparent sections, the same Emerald Green becomes brighter and more luminous. This interplay between saturation and light transmission gives the specimen an engaging visual range, with different areas coming into prominence as its orientation changes.

Its elongated, asymmetric outline offers several distinct presentations. A broad face rises towards an uneven upper contour, while narrower side views reveal projecting ridges, curved edges and shallow recesses. The silhouette changes noticeably with rotation, allowing the specimen to be appreciated both for its overall form and for the detail of individual surfaces.

The surface texture is particularly expressive. Finely textured areas alternate with smoother, reflective planes, producing a combination of delicate sparkle and broader vitreous highlights. On the principal face, a wide textured surface catches numerous points of light, while the adjoining contours carry more concentrated reflections that emphasise the relief of the piece.

Within the body, transparent windows alternate with translucent areas, visible inclusions and internal reflective planes. These features create layered depth, allowing the eye to move between the surface and the interior. Stronger illumination brings luminous Emerald Green passages into view, while changes in angle reveal different internal details beneath the brilliant exterior.

The specimen’s appeal rests in this combination of vivid Emerald Green, vitreous lustre and individual rough morphology. Its Tsavo provenance provides a clear geographical identity, while its varied surfaces and changing optical depth offer ample detail for close observation.

NOTABLE POINTS:
• Vivid Emerald Green
Expressive Emerald Green gives the specimen its principal visual identity and immediate appeal.

• Depth of Emerald Green
Thicker portions display concentrated Emerald Green, adding richness to the body.

More transparent areas allow light to pass through and reveal bright Emerald Green within the specimen.

• Brilliant Vitreous Lustre
Reflective surfaces produce crisp highlights that emphasise the relief and contours of the rough.

• Sculptural Asymmetric Form
An irregular elongated outline gives the piece a distinctive profile from several directions.

• Broad Textured Face
A prominent surface carries fine texture that breaks reflected light into numerous delicate highlights.

• Contrasting Surface Details
Smoother planes, angular ridges and shallow recesses offer varied details for close examination.

• Layered Internal Depth
Transparent windows and internal reflective planes create a visually complex interior.

• Engaging Side Profiles
Rotation reveals changing proportions, projecting contours and different passages of transmitted light.

• Distinctive Upper Contour
The uneven upper outline adds character and completes the specimen’s individual silhouette.

• Tsavo Provenance
The stated locality of Tsavo, Taita Taveta, Kenya gives the specimen a specific geographical identity.

• Collector and Lapidary Interest
Its Emerald Green, areas of transparency and expressive rough form invite appreciation from both perspectives.

COLLECTOR’S INTEREST:
For a collector of garnets, this tsavorite offers a combination of identifiable provenance and individual visual character. Its appeal extends from the vivid Emerald Green to the relationship between surface texture, lustre and internal depth. The broad principal face provides a strong display orientation, while the narrower profiles reveal additional details that make rotation and magnified observation rewarding.

The specimen also suits a collection exploring the relationship between gem material and rough mineral form. Its luminous Emerald Green windows demonstrate the visual qualities that attract attention to tsavorite, while the asymmetric outline and textured surfaces preserve the individuality of the rough. Presented with carefully directed light, these features can be appreciated together.

LAPIDARY POTENTIAL:
The vivid Emerald Green and areas of transparency make this specimen an interesting candidate for assessment by an experienced lapidary. An in person examination would establish how its internal features and available depth could accommodate faceting, a cabochon or a freeform design. Any cutting plan should consider the orientation that best presents the Emerald Green and makes effective use of the transparent areas. Its present sculptural form also offers scope for a bespoke setting incorporating the rough specimen.

Photography and transparency:
All photographs are taken under controlled lighting conditions using a macro lens, carefully selected to present each specimen as accurately as possible.
No filters, colour enhancement, or artificial saturation are applied.
The lighting setup uses a calibrated 5500K light source, replicating neutral daylight to reveal natural tones, surface features, and internal characteristics. Under warmer or weaker indoor lighting, colours may appear slightly different, which is normal.
The purpose of this photographic process is documentation and representation, not visual enhancement. Images are intended to reflect the specimen faithfully as it appears under balanced natural light conditions.
