The upper portion of the crystal is dominated by a vivid and luminous pink, carrying that iconic bubble gum intensity while retaining a natural softness that prevents it from appearing artificial or overly saturated. This pink zone is not flat or uniform. Instead, it breathes through the structure, shifting subtly in tone as light moves across its curved surfaces, occasionally deepening into richer raspberry nuances. What makes this specimen particularly distinctive is the seamless transition into a warm yellow to golden base. This chromatic gradient flows naturally through the crystal body, moving from pink into soft peach tones and finally settling into a honeyed golden yellow. The transition is neither abrupt nor chaotic, but rather smooth and organic, reflecting a gradual evolution of chemical conditions during crystal growth. The morphology is where this piece truly separates itself. Rather than presenting a classic prismatic habit, the crystal displays a highly sculptural form defined by rounded contours and a complex interplay of concave and convex surfaces. These natural curves give the specimen a soft, almost fluid appearance, as if the crystal had been gently shaped by pressure rather than sharply defined by rigid crystallographic boundaries. This rounded geometry enhances the way light interacts with the surface, producing soft reflections and diffused highlights across the body of the stone. Internally, the crystal retains a translucent structure that allows light to penetrate and disperse unevenly through the material. When illuminated from behind, the pink zone undergoes a dramatic transformation, intensifying into a vivid luxury pink that appears to glow from within. This optical response creates a striking contrast with the warmer golden base, giving the specimen a dual visual identity depending on lighting conditions. Subtle internal features and natural growth textures remain visible, reinforcing the authenticity of the crystal and adding depth to its visual presence. These inclusions do not interfere with the aesthetic but instead contribute to the sense of a natural object shaped over geological time. Material from Minas Gerais is widely recognised for producing some of the most expressive tourmalines in the world, yet pieces that combine this level of colour contrast with such a uniquely rounded and sculptural morphology remain distinctly uncommon. This is not merely a colourful crystal. It is a small sculptural form in mineral expression, where colour and shape merge into a single, highly aesthetic object.

Collector’s Interest: Tourmalines displaying a natural transition between pink and yellow are considerably less common than standard single colour specimens, particularly when the gradient is smooth and visually balanced as seen here. The added presence of a rounded and sculptural morphology further elevates this piece beyond typical crystal habits. Rather than relying solely on colour, the specimen offers a combination of form, texture and optical behaviour that appeals to collectors who value individuality and natural aesthetics. Specimens from Minas Gerais continue to be among the most sought after in the world, and pieces that deviate from classical crystal geometry while maintaining strong colour contrast are especially desirable. Lapidary Potential: Although the colour is attractive, cutting would eliminate both the natural gradient and the sculptural morphology that define the specimen. Its highest value lies in preservation as a natural crystal, where its form and colour relationship remain fully intact. —————— 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
