About Stone

CJ Ormiston supply and fit a range of beautiful materials which are customised in size and detail. We advise the most suitable materials for each project to suit our clients needs and lifestyle. Granites and quartzes are hard wearing and the preferred choice of most of our clients.

GRANITE

Granite is an igneous rock, essentially molten magma, which is cooled and then hardened below the earth's surface. Granite is therefore a very dense and durable natural stone, and has been used successfully for kitchen and bathroom surfaces. Density and porosity may vary, we can advise the best choice to suit your lifestyle.

MARBLE

Marble is generally a calcious stone, formed from oceanic deposits and then compressed under pressure (metamorphosed). The characteristic swirls and veins of many colored marble varieties are usually due to various mineral impurities such as clay, silt, sand, iron oxides, or chert which were originally present as grains or layers in the limestone. Green coloration is often due to serpentine resulting from originally high magnesium limestone with silica impurities. These various impurities have been mobilized and recrystallized by the intense pressure and heat of the metamorphism.

LIMESTONE

Limestone is a sedimentary rock composed largely of calcite and aragonite minerals, which are different crystal forms of calcium carbonate. Most limestone consists of skeletal fragments of marine organisms. Limestone is a porous material, suitable for fireplaces and architectural features, though the surface can suffer damage due to water acidity and other pollutants.

We use limestone for hearths, fireplaces, steps, cills and architectural features. Limestone found in the UK includes: Bath stone, Portland Stone

SLATE

Slate is a fine-grained metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash formed through metamorphism. It is a soft, porous material.

RECYCLED

We source recycled worktops, predominantly quartz, made up of recycled materials and quartz/ resin compounds. Recycled worktops perform as well as the standard quartz ranges
