ORBICULAR GRANITE TABLE TOP
Mount Magnet, Australia
One of the most striking forms of granite, this material is found in very few places in the world and the location near Mount Magnet in Western Australia is the most renowned (another mine opened recently in Finland). The incredible patterning is the result of concentrically-layered spheroidal masses formed through nucleation around a grain crystal in a cooling magma chamber. This beautiful table top was cut from a single large boulder and highly polished; orbicules of black, white and gray contrast beautifully with the predominantly gray granite ground, which is further highlighted by the tan blush that denotes the presence of a plagioclase feldspar. Appropriately presented in circular form, it measures 25 3/8 inches in diameter.
