巴西产最罕见的紫色帝王黄玉 • 0.70 ct • 千分之一样品 - 高度: 7.5 mm - 宽度: 4 mm- 0.14 g - (1)

DESCRIPTION:
Only one in every thousand Imperial Topaz crystals extracted from the mines of Ouro Preto displays this extraordinary purple colour, making it one of the rarest and most exceptional expressions of Imperial Topaz. This crystal embodies precisely that rarity, presenting a beautifully saturated natural purple pink colour within a remarkably transparent and brilliantly lustrous prismatic form. It belongs to a category of Imperial Topaz that is seldom encountered on the market and is immediately distinguishable from the far more familiar golden, orange and reddish material.

The crystal possesses exceptional visual purity and a refined, luminous body colour that moves between delicate violet pink, richer purple pink and subtle lavender depending on orientation and illumination. Light travels deeply through the prism, activating the colour from within and creating brilliant flashes across the internal growth structures. Under stronger illumination, the crystal becomes especially vivid, with the purple component gaining intensity while retaining the elegant pink undertone characteristic of this extraordinary Ouro Preto material.

Its morphology is equally compelling. The crystal is beautifully formed as an elongated natural prism, culminating in a sharply developed and highly attractive pyramidal termination. The termination gives the specimen a strong sense of completeness and symmetry, while the elongated vertical faces preserve fine longitudinal growth structures characteristic of natural Topaz crystallisation. The combination of transparency, balanced proportions and an exceptionally readable termination creates the appearance of a naturally formed gemstone rather than conventional rough material.

The vitreous lustre is outstanding. Broad prism faces act almost as natural windows into the crystal, producing brilliant reflections while simultaneously exposing its transparent interior. Internal crystalline features generate additional flashes and depth as the specimen is rotated, complementing rather than obscuring the extraordinary colour. The result is a crystal with a remarkable interaction between surface brilliance, transparency and saturated purple pink colour.

Ouro Preto, Minas Gerais, remains the historic world reference locality for Imperial Topaz, and its finest crystals are renowned for exceptional saturation, lustre and gem quality transparency. Within that already celebrated production, natural purple Imperial Topaz occupies an exceptionally rare position. The combination seen here of saturated colour, strong lustre, transparency and a beautifully developed termination gives this specimen significant mineralogical and collector relevance.

This is an enduring collector crystal whose appeal rests simultaneously on rarity, provenance, colour and crystallographic beauty. Purple Imperial Topaz from Ouro Preto is already a highly specialised field of collecting, and a crystal preserving this degree of transparency, saturation and natural form represents an especially captivating expression of one of Brazil’s most celebrated gemstone minerals.

NOTABLE POINTS:
• Exceptionally rare purple Imperial Topaz colour
Pinkish purple to purple is recognised among the rarest colour expressions produced by the Ouro Preto Imperial Topaz deposits.

• Saturated purple pink body colour
The crystal displays a sophisticated combination of violet, lavender and vivid pink nuances with excellent visual intensity.

• Outstanding vitreous lustre
Natural prism faces produce brilliant reflections that greatly enhance both colour and transparency.

• Beautifully developed natural termination
A sharply formed pyramidal crystal head gives the specimen excellent structural definition and collector presence.

• High natural transparency
Light penetrates deeply through substantial areas of the crystal, producing a luminous gem quality appearance.

• Strong internal light response
Direct and transmitted illumination activate vivid violet pink flashes throughout the crystal body.

• Elegant elongated prismatic habit
The upright proportions give the specimen a refined architectural form and immediately recognisable Topaz morphology.

• Preserved longitudinal growth structures
Fine natural vertical features remain visible along the crystal faces and record its original crystallisation.

• Rare combination of colour and morphology
Purple Imperial Topaz is itself scarce, while well formed transparent crystals with strong terminations are especially desirable.

• Historic Ouro Preto provenance
The specimen originates from the world renowned Brazilian district most closely associated with fine natural Imperial Topaz.

• Completely natural presentation
No cutting, polishing or treatment has altered the original crystal architecture or colour expression.

• Exceptional collector identity
Its rare colour, transparency, lustre and termination create an immediately distinctive specimen within any Imperial Topaz collection.

COLLECTOR’S INTEREST:
Purple Imperial Topaz occupies an exceptional position among collectible Topaz. Scientific gemological literature on the Ouro Preto deposits identifies pinkish purple to purple as the rarest colour produced in the district, with discoveries historically occurring only in extremely limited quantities. For advanced collectors, that rarity alone places specimens of this colour in a very different category from conventional Imperial Topaz.

The finest Imperial Topaz specimens are traditionally associated with Ouro Preto, Minas Gerais, where exceptional saturation, vitreous lustre, transparency and well developed natural crystals have established the locality as the international reference for the variety. This specimen brings those qualities together with the additional distinction of an exceptionally scarce purple pink colour.

Its collector appeal is strengthened considerably by the preservation of its natural prismatic morphology and sharply developed termination. Rather than presenting merely as coloured rough, it remains a complete mineral specimen in which the natural architecture, optical qualities and extraordinary colour can all be appreciated together.

LAPIDARY POTENTIAL:
The transparent body, saturated purple pink colour and strong brilliance provide excellent gemological potential. Careful orientation could produce a distinctive faceted gemstone, and its elongated proportions would also lend themselves naturally to a bespoke pendant or a refined single earring design.

Nevertheless, the rarity of the colour and the quality of the preserved natural termination give the crystal significant value in its untouched state. Any lapidary decision would therefore represent a choice between exploiting its gemstone potential and preserving an exceptionally uncommon natural Purple Imperial Topaz crystal from Ouro Preto.

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.
