Quartz is the second most abundant and hardest minerals on Earth. Quartz is crystallized silicon dioxide (SiO2), which is usually white or transparent, although it can be found in other colours. It is extracted from the ground where colours, pigments and grains are added to create quartz slabs. An Riocht Marble & Granite are sole agents for Vicostone  quartz  which is the best quartz available on the market today. We have worked with all the quartz manufacturers in the past but Vicostone is by far the best quality on the market now  



Granite is an igneous rock and is formed from magma. Granites usually have a medium-to coarse-grained texture and is one of the most durable and hard wearing stones and is an excellent choice for kitchen countertops. It is easy to maintain, does not scratch or stain easily and is ideal for high traffic areas like kitchen worktops. It can also be applied to bathrooms, flooring, cladding, fireplaces and monuments. It comes in over 2500 colours from every corner of the Earth.


Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. It is mainly used for flooring, bathrooms, fireplaces, cladding and monuments, but due to its natural beauty it has been applied to kitchen countertops in recent times. Marble is not as hard wearing as granite or quartz and needs extra care not to scratch or stain it.


Limestone is a sedimentary rock composed largely of the minerals calcite and/or aragonite, which are different crystal forms of calcium carbonate. Limestone is one of the softer stones available and is mainly used for cladding, monumental, kerbing, window sills, columns, pillars, steps and landscaping. An Riocht Stonecraft uses Irish Blue Limestone.
