Wood displays different grain patterns depending on which way they are cut - for example, the 'medullary ray' which can appear on oak furniture is a mark of good quality timber, these are just characteristics of the natural beauty of the wood. Wood veneers also allow distinctive patterns to be created on some surfaces, such as table tops and drawer fronts by the way slivers are arranged. All timber and veneer surfaces will change colour and mellow over time. New furniture will initially vary in shade from items that have been previously purchased. 

Marble

The Radius has been crafted from Italian Carrara marble, renown for its white and blue grey appearance.  Found in mountainous regions, marble is a calcium carbonate-based stone formed by extreme heat and pressure resulting in a crystalline material. Every piece has veins of mineral patterns which make up its unique appearance. Easy to polish and excellent heat resistance, marble is a durable surface however it is porous and care must be taken, especially with acidic spills. Marble will develop its own patina over time depending on the level of care you give it.
