Synonyms 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. |

Category 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 | 500 million years (Palaeozoic) |
Colouring minerals: | Feldspar (albite), white quartz, translucent Biotite, silver muscovite scales |
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.
Irregular gneissic granite with shining silver flakes.
Slight green hue.
Popular and typical usage
Petrology:Consists of 90% feldspar and quartz which cannot be seen with the naked eye due to the irregular contour of the grain. Black biotite has been partially converted to green chlorite, which gives the rock a light green shade. Silvery muscovite flakes give an unobtrusive glittering effect.
Petrogenesis:Formed during movement of the Alps. Clay and sand sediments underwent metamorphosis at high pressure and temperature.
