Calacatta Oro

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.	Calacatta d`Oro, Calacatta Gold, Calacatta di Sienna
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.	Marble
Petrographic assignment	Metamorphit – Marble
Age	150 Million years (Jurassic-Liasic)
Colouring minerals:	White calcite structured yellowish to reddish-brown by limonite or hematite
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.	3-4 (Soft)
Origin	Italy

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-grained, white to light beige marble of the Jurassic period (Lias) with yellowish-brown-grey decoration.

Petrology:A very fine-grained white marble with striking arabesques which vary grey to brownish-yellowish in colour. These differences in colour and pattern occur depending on the quarry it was mined. The name Calacatta originates from the Italian language describing the texture for marble with large-scaly structures. This term has become established for a number of deposits and varieties.

Petrogenesis: The Apuani marble area of the region of Carrara-Massa-Pietrasanta was generated during the Jurassic formation by a metamorphosis process covering a large region. Limestone complexes with different contents of organic contents and different quantities of clay minerals were re-crystallised to marble under high pressure and temperatures caused by folding-up of the Apennin mountain range. The residual clay, participating in decorating the arabesques, can be coloured lightly reddish or yellowish-brownish due to hematite or limonite enrichment.

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. :	Low
Porosity 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. :	Medium
