Within its minimal size lies a sophisticated dialogue between form, colour and transparency, where two distinct crystal bodies appear fused into a single harmonious entity. The upper section rises in a saturated aurora green tone, dense and luminous, forming a natural domed cap that crowns the crystal with depth and intensity. This green zone carries internal reflections and subtle textural features that respond dynamically to light, giving the impression of movement suspended within solid matter. Beneath it, the crystal transitions seamlessly into a colourless to icy white body of exceptional clarity, allowing light to pass through cleanly and revealing the internal architecture with striking precision. The colour transition is gradual and organic, without abrupt boundaries, creating a visual flow that enhances the sculptural quality of the specimen. Despite its minimal size, the crystal conveys a sense of structural confidence, with sharp terminations, vertical striations and a well defined geometry that speaks of high quality growth conditions. This piece exemplifies how scale does not dictate presence. Its refined proportions, elegant colour zoning and architectural balance elevate it far beyond its physical dimensions, making it a specimen that rewards close inspection and thoughtful appreciation. Specifications: Weight: 0.14 g Weight in carats: 0.70 ct Dimensions: 6 × 5 × 3 mm Origin: Minas Gerais region, Brazil Mineral species: Tourmaline (Elbaite) Crystal form: Natural bicolour prismatic crystal, bicrystal growth Colour: Deep emerald green transitioning to colourless white Transparency: Transparent to translucent Lustre: Vitreous Surface and structure: Strong vertical striations with sharp natural terminations Condition: Natural, unpolished, untreated specimen Notable Points: • Distinct bicolour formation with aurora green upper cap and colourless lower body • Exceptionally clean colour transition without harsh zoning lines • Architectural crystal geometry with strong vertical striations • Natural domed green termination enhancing visual depth • High internal clarity in the lower colourless section • Luminous green saturation concentrated in the upper crystal body • Balanced proportions creating a unified bicrystal appearance • Well preserved natural surfaces and sharp edges • Elegant fusion of two crystal growth phases into one structure • Minimal size yet high visual and structural impact • Excellent light interaction revealing internal textures and zoning Collector’s Interest: This specimen holds strong appeal for collectors who value crystal architecture, colour zoning and natural growth aesthetics over sheer size. Its refined bicolour composition and sculptural balance make it particularly desirable for advanced collections focused on tourmaline morphology and colour transitions. The minimal size enhances its rarity factor, demonstrating how precision and elegance can outweigh scale in collector significance. Lapidary Potential: Although already a complete and compelling crystal specimen, this tourmaline also presents lapidary potential for those interested in creative applications. The material is already shaped by nature into a form suitable for custom jewellery concepts, such as a ring or pendant, where the natural green cap and transparent body could be showcased without further alteration. Its structural integrity and clarity support both preservation as a crystal and imaginative use in bespoke designs. —————- Shipping and Handling: All orders are shipped by UPS express or National Express. • Dispatch time: within 1 to 2 business days after payment confirmation to catawiki • Transit time with Express service: up to 3 business days within europe and worldwide • A tracking number is always provided Photography and transparency: All photos were taken under controlled light conditions, carefully selected to reproduce the most accurate natural colour of each specimen.
