Black amber, also known as jet, is a type of organic gemstone formed from fossilized wood. Unlike traditional amber, which is formed from tree resin, black amber is created from the remains of decaying wood submerged in sedimentary deposits over millions of years. It is primarily composed of carbon and hydrocarbons, giving it its characteristic dark coloration ranging from dark brown to black.

Geological Origins

Black amber, also known as jet, has geological origins deeply rooted in ancient forests and sedimentary processes. Here’s an overview of its geological formation:

  1. Origin of Organic Material: Black amber forms from the fossilized remains of ancient wood, primarily from coniferous trees such as Araucariaceae, Cupressaceae, and Taxaceae. When these trees died, their wood was buried under sediment layers, preventing decomposition and facilitating fossilization.
  2. Burial and Compression: Over millions of years, layers of sediment continued to accumulate above the buried wood, exerting immense pressure. This pressure compresses the organic material, squeezing out water and volatile components, leaving behind a carbon-rich structure.
  3. Lithification: As the sedimentary layers solidify over time, the organic material undergoes a process called lithification, transforming into a compact, dense substance known as lignite or brown coal. This early stage of coal formation is crucial in the initial preservation of the wood.
  4. Subsequent Geological Processes: Further geological processes such as tectonic movements, heat, and pressure contribute to the transformation of lignite into jet. Heat and pressure gradually increase as sedimentary layers are buried deeper within the Earth’s crust, causing chemical changes that alter the composition and appearance of the organic material.
  5. Conversion to Jet: Under the right conditions of temperature and pressure, lignite undergoes a transformation into jet, a compact, homogeneous form of fossilized wood. This process, known as carbonization, involves the removal of volatile components and the rearrangement of carbon atoms, resulting in the characteristic black color and glossy appearance of jet.
  6. Exposure and Mining: Over geological time scales, tectonic activity and erosion may bring jet-bearing rock formations closer to the Earth’s surface. Jet deposits are then mined through various methods such as open-pit mining or underground excavation.

In summary, black amber or jet originates from the fossilization and transformation of ancient wood buried under sedimentary layers over millions of years. Geological processes such as burial, compression, lithification, and carbonization play crucial roles in its formation, resulting in a distinctive organic gemstone with unique properties and appearances.

Composition and Properties

The composition and properties of black amber, also known as jet, contribute to its unique characteristics and desirability as a gemstone. Here’s an overview:


  1. Organic Material: Jet is primarily composed of carbon, which originates from the fossilized remains of ancient wood. It also contains small amounts of hydrogen, oxygen, and other trace elements.
  2. Carbonaceous Material: The carbon content in jet is responsible for its black coloration and organic nature. It undergoes a process of carbonization during its formation, which involves the removal of volatile components and the rearrangement of carbon atoms.
  3. Trace Minerals: Depending on the specific geological conditions during formation, jet may contain trace minerals such as sulfur, iron, manganese, and others, which can influence its color and properties.


  1. Color: Jet typically exhibits a deep black color, ranging from dark brown to black. Its intense hue is due to the high carbon content and the absence of impurities.
  2. Lustre: Jet has a distinctive glossy or resinous lustre, which is a result of its fine-grained structure and smooth surface finish.
  3. Hardness: Jet has a relatively low hardness ranging from 2 to 4 on the Mohs scale. This makes it susceptible to scratching and abrasion, requiring careful handling and maintenance.
  4. Density: Jet has a moderate to high density, typically ranging from 1.3 to 1.4 g/cm³. This density contributes to its substantial feel and solid appearance.
  5. Transparency: Jet is typically opaque, meaning it does not allow light to pass through. However, certain thin sections or polished surfaces may exhibit slight translucency.
  6. Fracture: Jet exhibits a conchoidal fracture, meaning it breaks with smooth, curved surfaces resembling the interior of a seashell. This fracture pattern is characteristic of organic materials like jet.

Other Properties:

  1. Electrical Conductivity: Jet can acquire an electric charge when rubbed or polished, exhibiting triboelectric properties. This property has led to its historical use in jewelry and decorative objects.
  2. Thermal Conductivity: Jet has relatively low thermal conductivity, meaning it does not conduct heat well. This property has made it popular for use in mourning jewelry, as it remains cool to the touch.
  3. Chemical Stability: Jet is chemically stable under normal environmental conditions, resisting most acids and alkalis. However, it can be damaged by prolonged exposure to harsh chemicals or extreme temperatures.

In summary, black amber or jet possesses a distinctive composition and set of properties, including its carbonaceous nature, intense black color, glossy lustre, moderate hardness, and unique fracture pattern. These characteristics make it a sought-after gemstone for jewelry, decorative objects, and spiritual purposes.
