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.
Black Amethyst, Nero Ametista, Black and Gold, Star Galaxy, Black Galaxy, Nero Galaxy
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.

Age 1.4 billion years (Precambrian)
Colouring minerals: black pyroxene, bronze-colour broncite crystals
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.

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.

A fine to medium-grained, black gabbro with golden-yellow sparkling broncite scales.

Petrology: Gabbro: a dark, coarse-grained, intrusive igneous rock chemically equivalent to basalt. It is a plutonic rock, formed when molten magma is trapped beneath the Earth’s surface and cools into a crystalline mass.
The rock is a medium-grained, full-crystalline, regular stone consisting entirely of black pyroxenes (metal bearing silicate minerals) and of bronzite crystals of up to 1cm in size, uniformly distributed throughout the rock. Exceptionally, there may be a magnetite ore present. Bronzite is a silicate mineral with a bronze-hued shimmer which is often encountered in gabbroid rock.

Petrogenesis: Star Galaxy is a magmatite rock which is described as pyroxenite because of its mineralogical make up. A silicate-rich magma solidified beneath the primeval earth crust under highly stable cooling conditions. The result was the homogeneous graining of this recently discovered stone.

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.
