鲜艳的西瓜碧玺 • 1.45 ct • 霓虹粉色核心 与 强烈绿色外环 - 高度: 7 mm - 闊度: 5.5 mm- 0.29 g - (1)

Description:
This exceptional Watermelon Tourmaline cross section from Minas Gerais is defined by a bold pointed crystal outline and a vivid pink nucleus enclosed within a continuous green outer rim. The strong separation between these natural growth zones gives the specimen immediate character, while its balanced geometry creates a refined and highly recognisable watermelon structure.

At the centre lies a concentrated raspberry pink to magenta core with excellent chromatic presence. Its slightly rounded form becomes dramatically more luminous under transmitted light, transforming into an intense neon pink with vivid internal flashes. Fine crystallisation textures throughout the nucleus scatter illumination in multiple directions, giving the colour an active and almost incandescent appearance.

A delicate pale halo surrounds the pink centre and creates a clearly readable transition into the green outer zone. This narrow intermediate band increases the perception of depth and allows the successive stages of crystal growth to be observed with remarkable clarity. The outer rim ranges from fresh leaf green to deeper olive green under ambient light, becoming a brilliant neon green when illuminated from behind.

The specimen preserves the natural architecture of the original tourmaline prism, including its pointed upper profile, defined lateral faces and fine parallel growth striations. Bright vitreous reflections develop across the exposed surfaces, while internal veils and growth textures create additional optical movement without obscuring the principal colour zoning.

Its strongest quality lies in the transformation produced by light. Under normal illumination, the crystal displays a composed relationship between raspberry pink and natural green. Under backlighting, both zones become intensely luminous, creating a powerful neon pink and neon green display that confirms the exceptional optical character of this untreated Watermelon Tourmaline.

Notable Points:
• Vivid raspberry pink central core: The concentrated nucleus creates a powerful focal point with excellent chromatic presence.
• Brilliant neon pink response: Transmitted light dramatically intensifies the core and activates vivid internal flashes.
• Continuous green outer rim: The green zone remains clearly visible around the nucleus and defines the classic watermelon structure.
• Strong neon green transformation: Backlighting converts the outer rim into a bright luminous green with exceptional freshness.
• Clearly defined transitional halo: A pale intermediate zone separates the principal colours and increases the readability of the growth sequence.
• Distinct pointed crystal architecture: The natural shield shaped outline gives the specimen a strong and elegant identity.
• Excellent concentric zoning: The relationship between the pink nucleus, pale halo and green perimeter is immediately recognisable.
• Dynamic optical behaviour: The entire colour composition changes noticeably according to the direction and intensity of illumination.
• Preserved prism faces: Natural lateral surfaces retain the geometry of the original tourmaline crystal.
• Fine growth striations: Parallel surface lines provide visible evidence of natural prismatic development.
• Bright vitreous lustre: Reflective surfaces enhance the colour contrast, transparency and internal detail.
• Expressive internal crystallisation: Fine textures within the core scatter light and create a lively illuminated appearance.
• Untreated natural specimen: Its colour, zoning and internal architecture remain entirely natural.
• Strong collector presentation: The combination of vibrant colour, defined structure and neon illumination produces exceptional display appeal.

Collector’s Interest:
Watermelon Tourmalines with clearly separated pink and green zoning remain highly desirable among collectors. This specimen is particularly attractive for its vivid central nucleus, continuous green rim, pointed natural outline and dramatic neon transformation under transmitted light.

Lapidary Potential:
Although the transparent areas and strong colour could support selective cutting, any intervention would remove the natural concentric zoning and pointed crystal architecture. Its greatest value lies in preservation as a complete and highly expressive Watermelon Tourmaline cross section.
