At the centre, a well defined rose pink nucleus forms a rounded internal heart, softly luminous and clearly separated from the surrounding zone. This pink core is enclosed by an external perimeter that sits precisely between yellow and green, a chartreuse like tone that shifts subtly depending on light and angle, creating a rare and visually striking contrast. Rather than the classic green outer rim commonly seen in watermelon tourmalines, this specimen displays a yellow green outer zone with a translucent, almost citrus like freshness. The transition between the pink core and the outer rim is clean and organic, without harsh boundaries, allowing the colours to coexist in a harmonious yet highly uncommon configuration. The crystal retains clear longitudinal growth lines along the outer surface, preserving its natural prismatic character. Internal transparency is strong, allowing light to travel through both colour zones and enhancing the depth of the pink centre. This combination of rose pink with a yellow green perimeter is rarely encountered and gives the stone a distinctive identity within watermelon tourmaline material. Formed within Brazilian pegmatites, this specimen reflects the complex chemical environments responsible for such unusual zoning. It is a stone that stands out not by size, but by colour architecture and rarity of palette, offering both visual intrigue and strong collector appeal. Specifications: • Weight: 0.32 g • Weight in carats: 1.60 ct • Dimensions: 10 × 10 × 10 mm • Origin: Minas Gerais Brazil • Material: Natural watermelon tourmaline • Crystal form: Natural crystal fragment • Colour: Rose pink core with yellow green outer rim • Colour zoning: Distinct concentric zoning with clean internal transition • Transparency: Translucent • Lustre: Vitreous • Treatment: None • Form: Natural crystal with preserved growth features Notable Points: • Rare colour combination featuring a rose pink core with a yellow green perimeter • Uncommon departure from the typical green rim seen in classic watermelon tourmalines • Clean and organic colour separation without abrupt chromatic breaks • Strong internal translucency enhancing depth and colour visibility • Preserved longitudinal growth lines along the crystal surface • Compact yet visually powerful specimen due to its colour architecture • Natural, untreated material formed in Brazilian pegmatites Collector’s Interest: Collectors of watermelon tourmaline often seek strong zoning, but specimens combining pink with a yellow green outer rim are significantly less common than standard green rim examples. This stone offers a distinctive palette and well balanced internal structure, making it particularly appealing to collectors focused on unusual colour relationships and natural crystal character rather than size alone. Lapidary Potential: The clear internal zoning and compact proportions offer interesting possibilities for careful lapidary work, particularly for preserving the pink core within a contrasting yellow green frame. Any cutting approach would need to respect the natural colour boundaries, as the stone’s value lies primarily in its rare chromatic configuration. Equally, it remains highly compelling as a preserved natural specimen. —————— 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.
