Natural rough diamond, weight 0.16 g (0.80 ct), dimensions 5.5 x 5.5 x 5.5 mm, vivid blood red colour, from Lunda Norte, Angola, rounded natural crystal morphology and unpolished.
Description from the seller
Description:
Like a drop of vivid blood red captured in crystalline form, this remarkable natural rough diamond reveals a colour that feels powerful, saturated and alive. Its tone is not flat or uniform, but layered and expressive, shifting between luminous blood red highlights and deeper, more concentrated crimson zones that create a natural internal dynamism.
This is a diamond that captures attention instantly through colour alone. The red is energetic, rich and highly expressive, with a visual intensity that stands out even under subtle lighting. It carries a striking vivid blood red luminosity, reminiscent of one of the most desirable red tones in the gem world.
The crystal presents a compact and naturally rounded morphology. Its shape is harmonious and organic, with softly defined transitions between surfaces that give it a refined and visually pleasing presence from different angles.
The surface is composed of dense micro crystalline textures, forming a complex network of small reflective planes. These structures interact strongly with light, producing scattered flashes of adamantine lustre across the stone. Unlike polished diamonds, the brilliance here is fragmented and dynamic, creating a constant interplay of sparkle and depth.
Colour distribution is naturally irregular, with certain areas displaying stronger concentration of vivid blood red, while others soften into lighter red tones. This variation enhances the perception of depth, making the diamond feel almost internally illuminated.
Transparency is naturally balanced by the density of colour, contributing positively to the visual identity of the piece. Light is absorbed and remitted across the surface rather than simply transmitted, intensifying the richness of the vivid blood red appearance and reinforcing its bold character.
The lustre is distinctly adamantine, expressed through multiple micro reflections that give the surface a lively and energetic appearance. Combined with its rounded natural form, this creates a strong three dimensional presence.

Collector’s Interest:
Rough diamonds displaying red coloration occupy a particularly fascinating position within the world of natural diamonds. In specimens such as this, the colour can appear more organic and expressive, interacting directly with the original crystal surface and natural internal structure.
This piece stands out through its combination of intensity, vivid blood red appearance and rounded natural form. Its morphology enhances the way light interacts with the micro crystalline surface, while the saturated red tones create an immediate visual response.
For collectors, this specimen offers character in its most natural expression, combining the unmistakable identity of rough diamond with an unusually vivid and expressive red appearance.
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.

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.
