Mineralogical characteristics
Jet is a unique material within the mineral world, known for its deep and opaque appearance. Although it is often considered a gem, technically it is a mineraloid, since its origin is not inorganic but organic. It is a variety of lignite, a type of fossil coal with a high carbon content.
The characteristics of jet are due to its formation process: it comes from wet wood or fallen trunks that were buried in marine sediments and subjected to strong pressure for millions of years. This fossilization process created a compact, light material with a smooth texture.
Jet has an intense black color, although some specimens may show dark brown tones or warm reflections. Due to its shine and polished feel, many cultures have compared it to “black amber”. Some fragments contain small pyrite inclusions, which add metallic flashes and make the pieces even more striking for jewelry.
The origin of jet is strongly linked to ancient coastal regions, especially areas where forests once existed near the sea. For this reason, it frequently appears in rocks of marine origin, sedimentary caves and fossil cliffs. In ancient times it was already valued as a protective amulet and was used both in ornaments and in powder mixed with water or wine for traditional remedies.
The most important deposits are found in England (Whitby) and Spain, especially in Asturias and Teruel. There are also deposits in France, Germany, Poland, India, Turkey, the United States, Russia, Portugal, Mexico and Venezuela. Its lightness, ease of carving and deep color have made jet one of the most emblematic materials in traditional craftsmanship and one of the most respected protective stones throughout history.

Therapeutic properties
The properties of jet have been recognized for centuries in spiritual and energetic practices. It is known as a stone of protection and cleansing, capable of absorbing and deflecting negative energies from the environment. Its connection with the 1st chakra relates it directly to grounding, stability and inner strength. Wearing jet helps one feel more present, secure and centered, especially in moments of tension or major change.
On an emotional level, jet encourages calm and reduces mental exhaustion. Its dense and protective energy acts as a shield that helps maintain clarity and prevents external influences from affecting mood. It is also considered a useful stone for those seeking to regain self-confidence, as it helps stabilize unstable emotions and reinforce personal security.
Spiritually, jet is used to cut harmful energetic ties and protect against envy or the evil eye. Its ability to absorb emotional burdens makes it an excellent ally for sensitive or empathetic people. In addition, it is said to encourage material protection, which is why many people use it as an amulet to protect businesses and finances, attracting order and economic stability.
Its deep energy, comparable to the calm embrace of the earth, makes jet an ideal mineral for those seeking balance, protection and inner renewal.
