Fossil Black

Stones can have many aliases. This is due to language differences, supplier choice, coloquial trends or slang, or sometimes errors and ambiguity between rocks. Read more here.
Nero Fossil, Galaxia, Galaxy, Morocco Black
Commercial classification sometimes differs to the scientific, geological designation. In particular, some limestones are deemed marble especially if they take a high polish. Read more here.
Petrographic assignment Sedimentary limestone with orthoceras
Age approximately 395-345 million years (Devonian)
Colouring minerals: Calcite, coloured black by carbon-like substances and low bitumen contents
Average hardness
MOHS is the standard scale of hardness for minerals 1-10, with 10 being the MOHS of diamond. We also use the broad terms Hard and Soft for simplicity. Read more here.

Origin Morocco


The images of each stone aim to give a faithful representation of the structure and colouring. The close-ups are generally taken from a sample around 100mm in height to get the detailing of the grain and crystals. The slab images are usually between 2000x1000mm and 3000x1900mm approximately, to give a more overall picture of the pattern. This is for guidance only, when seeking a specific pattern and colour matching, please obtain a sample or arrange for the slab to be viewed in person. When placing the order, you may require a photo of the actual slab before production, the colour and character can vary significantly even throughout the same block within natural materials. Also monitor calibration, camera settings and lighting can all effect how the materials are perceived.

Petrology:A grey-black to black sludge, which is covered with orthoceras, the shells of fossil cuttlefish / squid. The shells are conical and have clearly visible chambers. The animal itself, of which obviously no residues are left, lived in the front part of the housing, while the empty chambers were used as ballasts with air and water. After the animal died these were filled with a small portion of sediment and the rest with crystalline lime spar. Such a large number of orthoceras are only found in this stone.

Petrogenesis:Lime spar is a sedimentary rock. In this case, it is a so called sludge limestone, the dark colour of which is caused by organic substances (bitumen). Such limestone is only generated on the sea bed in an oxygen-starved environment.

Wear Resistance
A high wear resistance will often mean a material is suitable for flooring and outdoors. Its is good for work surfaces as it will take some punishment before marking or losing its polish. Softer materials benefit from being re-worked more easily should the need arise. They can also more readily mature into their settings or be antiqued by design. People often overlook the less hard wearing stones for fear of maintenance and longevity issues. Whilst there are some valid concerns there is no rule for everyone, choose first what you like then decide on the practicality of the options. Some people appreciate the maturation and the patina taken on by some natural materials, others prefer a pristine look that will change little over time.
Every natural stone has a degree of water absorption. Sealing products exist to stop water ingress and protect against staining, but some stones are more susceptible than others. A highly polished surface is also more resistant to fluids than the rougher, more open surfaces of honed and brushed finishes. All spills should be wiped up in good time to prevent stains and marks.
