Description: This natural Tsavorite crystal immediately distinguishes itself through its remarkably preserved pseudo cubic crystal habit, a morphology that is highly desirable among collectors of gem crystals. Rather than appearing as an irregular fragment, the specimen retains a naturally balanced architectural form, with broad crystal faces, sharp edges and a well proportioned termination that gives it an exceptionally aesthetic three dimensional presence. Its colour displays a rich, highly saturated emerald green produced by chromium and vanadium, the chromophore elements responsible for Tsavorite’s celebrated brilliance. Light penetrates the crystal with surprising efficiency, activating vivid internal reflections that travel throughout the transparent body and produce an energetic, almost luminous appearance from multiple viewing angles. The crystal exhibits excellent transparency across much of its volume, allowing its internal structure to become part of the specimen’s visual appeal. Fine natural growth features and subtle internal veils are visible beneath the surface, enhancing its geological authenticity while adding depth and complexity without diminishing the overall brightness of the crystal. One of the most attractive characteristics of this specimen is its naturally preserved crystal architecture. The broad crystal faces display delicate growth textures together with exceptionally sharp edge junctions, while the termination retains an elegant symmetry that reinforces the crystal’s geometric identity. Depending on the angle of observation, the specimen alternates between a compact cubic silhouette and a slightly elongated architectural form, giving it a dynamic visual character despite its modest dimensions. Natural vitreous lustre is exceptionally strong across the crystal faces, producing crisp reflections that contrast beautifully with the transparent interior. Under direct illumination, the polished appearance of the natural faces combines with the saturated green body colour to create a vivid interplay of brilliance, transparency and depth. Originating from the famous Tsavo region of Taita Taveta County, Kenya, this untreated Tsavorite represents one of the world’s finest green grossular garnets. The region remains internationally recognised for producing crystals of exceptional colour and quality, making naturally preserved specimens with attractive crystal morphology increasingly sought after by mineral collectors. Combining excellent colour saturation, high transparency, a remarkably aesthetic pseudo cubic crystal habit and beautifully preserved natural crystal faces, this specimen possesses a refined mineralogical character that is equally appealing as a collector’s crystal and as an outstanding example of natural gem rough.

Rather than being valued solely for potential cutting, specimens such as this allow collectors to appreciate the crystal exactly as it formed within its geological environment. Its combination of vivid emerald green colour, excellent transparency, strong vitreous lustre and balanced crystal architecture gives the specimen outstanding display quality while preserving the natural features that make untreated Tsavorite one of the most desirable collector gemstones from East Africa. Lapidary Potential: The crystal possesses transparent areas capable of producing small faceted material with attractive colour and brilliance. Nevertheless, its greatest value lies in the preservation of its naturally terminated pseudo cubic morphology, where the harmony between crystal habit, transparency and vivid green colour can be fully appreciated as a complete mineral specimen. Although it holds potential as cutting rough, this piece also carries significant value in its natural form, and any decision to cut should be carefully weighed against the loss of its current visual complexity. ————— Shipping and Handling: All orders are shipped by Portuguese National Post and UPS • Dispatch time: within 1 to 3 business days after payment confirmation to Catawiki • Transit time service: between 2 to 5 business days within europe and worldwide, depending on destination national post. • A tracking number is always provided 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. Identification and ethics: All specimens offered are natural and described to the best of our knowledge, based on direct sourcing, professional experience, and information provided by trusted suppliers working at the origin. Every effort is made to ensure transparency and accuracy regarding identification, locality, and general characteristics, avoiding misleading statements about treatment, provenance, or nature. Customs and import taxes: Any customs duties, import fees, or local taxes applied by the destination country are entirely the responsibility of the winning bidder. These charges are not included in the auction price or shipping cost and are determined by the buyer’s local authorities. Guarantee and resolution: Customer satisfaction is important. In the unlikely event of an issue such as loss, damage, or discrepancy, please contact us promptly through Catawiki’s messaging system. Each case is handled individually and fairly, with appropriate solutions offered when justified. Appreciation and commitment: We sincerely thank you for your trust. Our work focuses on careful selection, accurate representation, and respectful presentation of mineral specimens with character and interest. Each piece is chosen for its individual qualities rather than speculative or financial considerations. We aim to provide a transparent, reliable, and consistent experience for collectors at all levels. With gratitude, GemPulse Minerals
