珍贵的巴西帝王托帕斯 • 1.65 克拉 • 金香槟色 来自 奥鲁普雷托 - 高度: 14 mm - 宽度: 4.5 mm- 0.33 g - (1)

DESCRIPTION:
Among all coloured topaz varieties, Imperial Topaz remains one of the rarest and most prestigious gemstones ever discovered. This exceptional natural crystal from Ouro Preto, Minas Gerais, Brazil, displays a beautifully elongated prismatic habit combined with remarkable transparency, strong internal luminosity and a deeply saturated Golden Champagne colour that immediately identifies it as premium collector material.

The crystal possesses excellent optical clarity throughout much of its body, allowing light to penetrate deeply and illuminate the specimen from within. Natural internal growth features remain visible, adding depth and geological authenticity without overwhelming the transparent structure. Under stronger directional illumination, the body becomes intensely luminous, with bright golden reflections travelling vertically through the crystal and concentrating particularly around the lower section and prism edges.

Its colour is exceptionally attractive and more saturated than the delicate champagne tones observed in many Imperial Topaz crystals. Under ambient light, the specimen presents a refined Golden Champagne appearance, while direct illumination activates richer Golden Honey and warm amber tones. This transition creates a vivid internal glow that remains visible from multiple viewing angles and gives the crystal considerable display presence.

The naturally elongated prism preserves well defined vertical faces decorated with fine longitudinal growth striations. These surface features interact continuously with light, producing narrow reflective flashes that emphasise the height and elegance of the specimen. The termination remains naturally preserved and displays original crystallisation textures, completing the crystal without polishing, reshaping or artificial intervention.

Ouro Preto is internationally recognised as the historic source of the world’s finest Imperial Topaz. The combination of saturated golden colour, strong transparency, elegant prismatic architecture, vitreous lustre and authentic natural growth features makes this specimen a highly expressive example of the qualities that have established this Brazilian locality as legendary among gemstone and mineral collectors.

NOTABLE POINTS:
• Saturated Golden Champagne colouration
The crystal displays a rich and expressive golden tone with significantly stronger saturation than paler champagne examples.
• Golden Honey activation under direct illumination
Focused light intensifies the body into warmer honey and amber tones, creating a vivid internal glow.
• Excellent natural transparency
Light penetrates deeply through the crystal, revealing both its colour purity and internal architectural depth.
• Strong vitreous lustre
The prism faces reflect illumination with bright, clean flashes that enhance the overall visual quality.
• Elegant elongated prismatic habit
The slender vertical architecture gives the specimen excellent balance and a refined collector presentation.
• Naturally preserved termination
The crystal head retains original crystallisation textures and remains completely unpolished and unmodified.
• Fine longitudinal growth striations
Delicate vertical lines record the natural development of the crystal while creating attractive directional reflections.
• Expressive internal growth structures
Natural planes and delicate internal features add mineralogical complexity without obscuring the transparent body.
• Strong multi angle light performance
The saturated colour and reflective prism faces remain visually active as the crystal is rotated.
• Authentic Imperial Topaz from Ouro Preto
The specimen originates from the world’s most celebrated locality for naturally coloured Imperial Topaz.
• Completely untreated natural material
Its colour, transparency, lustre and structural characteristics are entirely natural.
• Premium collector presentation
The combination of colour saturation, transparency, prism development and provenance creates a highly desirable display specimen.

COLLECTOR’S INTEREST:
Imperial Topaz from Ouro Preto occupies a privileged position among the world’s most desirable collector gemstones. Crystals that combine strong golden saturation with high transparency and a clearly preserved natural prism are particularly appreciated, as these qualities reveal both the gemological and crystallographic importance of the material.

This specimen distinguishes itself through the intensity of its Golden Champagne colour and the way that colour responds to illumination. The transparent body allows golden light to move throughout the crystal, while the internal structures and longitudinal striations preserve a clear record of its natural formation.

Its legendary provenance further reinforces its collector appeal. For collectors of Brazilian gemstones, naturally coloured topaz and transparent prismatic crystals, this specimen represents an attractive and highly expressive example of genuine Ouro Preto Imperial Topaz.

LAPIDARY POTENTIAL:
The crystal possesses sufficient transparency and colour saturation to offer genuine lapidary potential. A skilled cutter could potentially recover a beautiful golden gemstone, particularly by selecting the cleanest transparent areas and orienting the material to preserve its strongest colour.

However, cutting would permanently remove the elongated natural prism, preserved termination, longitudinal growth striations and complete geological identity of the specimen. Its greatest value may therefore remain in its present natural form, where both its gem quality characteristics and crystallographic architecture can be appreciated together.

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.

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.
