The body is defined by a vivid, saturated pink tone, intense and alive, far removed from pale or diluted hues. Its colour carries a luminous vitality that immediately draws the eye, expressing the strength and purity of ruby in a natural, unrefined state. As the piece is rotated, subtle green nuances emerge along the sides and rear, forming a quiet counterpoint to the dominant pink core. These green mineral textures appear like natural accents, gently framing the ruby rather than competing with it. They introduce contrast, depth and a sense of geological dialogue, enhancing the visual richness of the specimen without diminishing the ruby’s authority. The surface shows raw crystalline textures, with areas of fractured lustre that catch light unevenly, creating shifting reflections across the stone. This interplay between colour, texture and form gives the piece a sculptural quality, where the ruby feels both powerful and organic. It is a specimen that rewards close inspection, revealing new details with every change of angle, and conveying a strong sense of natural character and authenticity.

The vivid pink tone, combined with minimal matrix interference, places this specimen above typical ruby in matrix pieces. Its expressive surface and contrasting green mineral accents create a visually engaging and well balanced specimen suited for advanced collections focused on natural ruby occurrences. Lapidary Potential: While highly attractive as a natural specimen, this ruby may also interest lapidaries experienced in working with complex crystal forms. Any lapidary approach would need to respect the stone’s structure and colour zoning, with selective cutting potentially enhancing its vivid hue. However, its strongest value lies in its natural state, where its colour, texture and geological integrity are fully preserved. —————— 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.
