It is concentrically banded with white, yellowish gray, olive gray, grayish orange, and light to dark gray brands. It also may be white to gray, white and gray marbeled. It becomes patchy pink and red, satiny or waxy luster when heat-treated. Occassionally has oolite inclusions. It has a oolitic texture that is coarse to medium, opaque with a dull to waxy luster. Deposits occur in a dolomite matrix as large spherical masses up to 50 cm in diameter, often with hollow, quartz-lined cores.
