What are Carbon Diamonds (Black Diamonds)?
Carbonados Diamonds , often called Black Diamonds , are an extremely rare and enigmatic form of polycrystalline natural diamond . Unlike transparent monocrystalline diamonds (white gems or industrial diamonds), Carbonados are opaque, porous masses of microscopic diamond crystals, with a composition that includes small amounts of graphite and amorphous carbon. Their black color is due to the presence of these inclusions.
Its origin is a subject of scientific debate, with theories suggesting a deep-Earth origin, a meteorite impact, or even an extraterrestrial origin. What is indisputable are its unique properties:
- Natural Polycrystalline : Like Ballas Diamonds, they are composed of millions of tiny diamond crystals, giving them exceptional strength.
- Extremely Hard and Uniform : They are incredibly hard and wear-resistant, even in all directions (isotropic in their hardness), making them ideal for cutting and grinding applications where hardness and toughness are paramount.
- Porosity and Unique Appearance : Their porous texture and opaque black color clearly distinguish them from other diamonds. This color has made them very popular in avant-garde jewelry designs.
- Fracture Resistance : The absence of large cleavage planes makes them less prone to fracture than single-crystal diamonds.
- Geographic Rarity : They are only found in alluvial deposits in Brazil and the Central African Republic, making them extremely rare and valuable.
Characteristics and Specifications of Carbon Diamonds:
We market Carbon Diamonds with precise specifications for industrial and jewelry applications:
- Color : From deep, uniform black to grayish or mottled tones. For jewelry, deep, glossy black is valued.
- Shape and Size : Available in the rough in irregular shapes, from small grains to large specimens weighing several hundred carats. For jewelry, they are often cut into faceted shapes (although faceting only reveals the opaque black, not the brilliance of clear diamonds) or used in their natural or lightly polished form.
- Density and Porosity : Variables depending on the specimen.
- Industrial Quality Grade : Classified by their strength, toughness and absence of major internal fractures.
- For Jewelry : Selected for their color, uniformity, shape and, if applicable, their polish to maximize their aesthetic appeal.
Main industrial and jewelry applications of Carbon Diamonds:
Carbon Diamonds are a high-value niche material, used in applications where their unique properties are essential:
- High-End Designer Jewelry :
- Faceted Black Diamonds : Popularized by designers and luxury brands for alternative engagement rings, pendants and earrings, offering a bold and modern aesthetic.
- Rough or Polished Black Diamonds : Used in organic and contemporary designs, highlighting their natural shape and texture.
- Men’s Jewelry : Their dark color and hardness make them attractive for men’s jewelry.
- High Performance Drilling Tools :
- Oil and Gas Drilling Bits : Their extreme hardness and fracture resistance make them exceptional for drilling very hard and abrasive rock formations, especially in the past. Although synthetic PCDs have now been developed that often outperform them in performance and cost for many applications, Carbonados retain a place in very specific applications due to their natural hardness and toughness.
- Mining and Geological Drilling : In drill bits and tools for extremely hard rock.
- Precision Abrasives :
- In certain polishing and grinding applications where uniform abrasion and superior wear resistance are required.
Marketing formats:
We supply Carbon Diamonds in different formats and presentations, according to your needs:
- Rough Carbonated Diamonds : Uncut and unpolished, graded by size and quality.
- Faceted Black Diamonds : In standard or custom cuts for jewelry.
- Cabochons or Polished Smooth Shapes : For jewelry.
- Industrial Tool Grains : Crushed and classified according to the desired granulometry.
- Specialized packaging : In secure and discreet containers, guaranteeing the protection and traceability of the material.
Logistics are tailored to each destination and volume, complying with strict national and international regulations for the transportation of gems and high-value industrial materials, including the Kimberley Process, where applicable.
Advantages of working without intermediaries
