DESCRIPTION: The warmth of sunset. The brightness of an ember. This natural rough diamond displays an expressive orange appearance, bringing together luminous tangerine tones, deeper amber passages and golden highlights across a richly textured crystalline surface. Orange establishes its identity immediately. The colour moves visually between fresh citrus brightness and warmer, more concentrated tones, creating a palette with both energy and depth. Bright reflections punctuate this warm background, like sunlight catching the edges of glowing embers. Under suitable illumination, translucent passages reveal a more luminous orange expression. Golden orange highlights emerge between denser amber areas, giving the body an appealing sense of depth. The effect is particularly engaging where light passes through the material and reveals colour beneath the reflective exterior. Its rounded to irregular natural form provides an organic frame for this palette. Changes in contour and surface direction create different arrangements of light and shadow, allowing the specimen to offer several attractive viewing perspectives without relying on a single defined silhouette. The exterior carries an intricate combination of small reflective planes, ridges and shallow depressions. Broader surfaces interrupt the finer texture, creating a varied relief that becomes increasingly apparent during close observation. These details give the orange colour a sculptural setting, with brighter passages following exposed features and deeper tones gathering in shaded areas. Adamantine lustre adds crisp definition to the display. Individual planes catch the light in sharp, almost white flashes, contrasting with the saturated orange appearance around them. As the viewing angle changes, these reflections shift across the surface, bringing different details into focus. Variations in translucency contribute to the specimen’s visual complexity. Some passages allow more light into the body, while others remain denser and more subdued. Together, they create a layered appearance in which luminous orange, golden accents and deeper amber tones remain closely connected. According to the provenance information transmitted by the previous collector, this diamond originates from Lunda Norte, Angola. It remains in its complete natural rough state, uncut and unpolished. The specimen is not accompanied by laboratory documentation, and the origin, distribution and stability of its orange colour appearance have therefore not been scientifically determined. The result is a warm and expressive rough specimen whose appeal unfolds through colour, texture and reflection. Its orange appearance provides the immediate attraction, while the finely varied exterior gives the eye a succession of details to explore.

COLLECTOR’S INTEREST: This specimen offers a collecting interest centred on its warm orange appearance and richly textured rough form. The colour provides an immediate point of attraction, while the relationship between tangerine brightness, golden highlights and deeper amber passages gives it a more varied visual character. Its surface contributes equally to that appeal. Small reflective planes and broader exposed areas catch the light differently, creating a changing arrangement of highlights across the exterior. Close observation reveals how these reflections emphasise individual ridges, depressions and transitions in relief. The rounded to irregular form allows the colour and texture to be explored from several perspectives. Different orientations bring forward different combinations of luminous orange, shaded amber and sharp surface reflections, making the specimen engaging beyond a single display angle. The specimen is not accompanied by laboratory documentation, and the origin, nature and stability of its orange colour appearance have therefore not been scientifically determined. For collectors, its interest resides in the combination of natural rough diamond identity, distinctive visual coloration, expressive light behaviour and provenance attributed to Lunda Norte, Angola. For a collection organised around colour and rough crystalline character, this piece contributes a warm, energetic presence. Its individuality lies in the way its orange appearance interacts with the existing surface relief, preserving an expressive relationship between colour, form and light. LAPIDARY POTENTIAL: This natural rough diamond may offer potential for jewellery design, polishing, faceting or preservation in its original form. However, as the origin, distribution and stability of the colour have not been laboratory determined, colour retention during cutting, polishing or any other lapidary procedure cannot be guaranteed. Any lapidary work should be assessed and carried out by a qualified professional, taking into consideration the internal structure, inclusions and colour distribution of the specimen. Preservation would retain the relationship between the orange appearance, textured exterior and scattered adamantine reflections. These features define the specimen’s current character and provide a strong basis for appreciation in its rough state. A bespoke display or professionally designed mount could offer an alternative presentation while keeping the principal surfaces visible. Such an approach would allow the warm colour palette and sculptural relief to remain the focus, with minimal alteration to the existing form. ——————- 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. • A tracking number is always provided 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. Guarantee and resolution: Customer satisfaction is important.
