The name "bluestone" is not a geological term and does not fall within any distinct category such as igneous, sedimentary or metamorphic. The name "bluestone" represents different rock types, so for example bluestone found in the UK can be different stone altogether when compared with the 2 prominent varieties of bluestone found in Australia. In Victoria, bluestone generally refers to a basalt, formed from the rapid cooling of lava, whereas in South Australia the name bluestone is generally given to a form of slate. Bluestone can be used indoors and out – for cladding, paving, stairs, coping, kitchen and bathroom counter tops, pool surrounds, garden edging, commercial and domestic flooring and retaining walls. Bluestone has a high degree of slip resistance. Victorian bluestone will generally be black or grey, while bluestone slate has a more beige colour.
