Description from the seller

**IMPORTANT DISCLAIMER**
LIMITED EDITION COLLECTION

This lot is part of a strictly limited five-piece collection.
This is number 3 of 5

Each Watermelon Tourmaline in this collection is presented as a unique entry, forming a complete limited set of 5 museum grade slices, all selected for exceptional clarity, symmetry, vivid colour zoning and outstanding rarity. Buyers following the series may pursue the full 5 piece collection across consecutive weekly auctions.

——————-

Description:
A captivating slice of natural Watermelon Tourmaline from the famed pegmatites of Minas Gerais, displaying the classic tri phase zoning that elevates this material into the realm of true collector pieces. Its core presents a vivid rose pink nucleus, rounded yet well structured, glowing with excellent saturation and internal luminosity. This pink heart is embraced by a soft white transition ring, a highly desirable intermediary layer that diffuses the colour gently outward before merging into the saturated green perimeter.

The green rim is harmonious, evenly toned, and beautifully translucent, framing the inner colours with definition and balance. The chromatic boundaries are clear and clean, reacting beautifully under direct light and revealing the natural architecture of the slice without interruption.

The only feature distinguishing this slice from an AAA grade specimen is the natural protuberance at the top edge. This is not a fracture or damage; it is a genuine growth remnant, the point where an additional crystal segment began to form before being naturally intersected. Rather than reducing the value, this feature gives the slice unique individuality, a structural fingerprint found only in naturally formed tourmalines. Everything else, colour, zoning, translucency and internal purity, remains at museum grade level.

A refined, characterful slice, graded AA solely due to this organic asymmetry, yet retaining every other quality seen in top tier Brazilian Watermelons.

Specifications:
• Weight: 0.58 g
• Carat weight: 2.90 ct
• Dimensions: 9 x 8 x 4 mm
• Origin: Minas Gerais, Brazil
• Material: Natural watermelon tourmaline
• Variety: Museum grade slice
• Colour: Vivid pink core with white transition and saturated green rim
• Transparency: Translucent with no black dots
• Treatment: None
• Form: Natural slice with no black inclusions.

Notable points:
• Rare tri chromatic zoning with vivid pink nucleus, white diffusion ring and sharply saturated green rim
• Clear internal translucency allowing full light passage and colour glow
• Strong chromatic boundaries, unusually well defined for a slice this size
• Unique natural protuberance giving the slice individuality without affecting structural integrity
• Absence of black inclusions or disruptive fractures
• Preserved museum grade interior symmetry despite the organic outer irregularity
• Typical Brazilian pegmatite formation with high architectural clarity

Collector interest:
An excellent slice for collectors seeking mineral pieces with strong chromatic architecture and natural individuality. Its museum grade zoning combined with its organic top growth signature enhances desirability within high end Watermelon Tourmaline collections.

Lapidary potential:
Suitable for bespoke jewellery framing, though equally compelling as a preserved specimen due to its colour zoning, translucency and character defining natural growth feature.

Each order is handled with professional care from selection to dispatch, ensuring a smooth and trustworthy process.

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.
