marble

Marble is a hard stone, typically white or light yellow, polished smooth and shiny, used in making walls, floors or sculptures.

A marble is a small ball made of coloured glass. Marbles are usually used as toys.

If something is marbled it has the streaked or swirled appearance of certain types of marble.

If a piece of meat has great marbling, it is interlaced with fats and its appearance resembles that of marble.
