    • n ultramarine A beautiful natural blue pigment, obtained from the mineral lapis lazuli, a variety of haüyne. This stone occurs in Siberia, Persia, Tibet, and some other localities. (See lapis lazuli, under lapis.) Small golden specks of iron pyrites are usually scattered through it. To prepare the pigment, selected pieces are heated, and cooled in water, producing disintegration. The powder is then purified by repeated washings, the several wash-waters depositing pigments of different depths of color, the gray powder known as ultramarine ash being the last and least valuable product. Ultramarine is very permanent under all conditions, and is, in color, the purest blue available. Its use is limited, however, by its great cost, and also by the fact that artificial ultramarine is practically as valuable. The color of both natural and artificial ultramarine is a rather dark and intensely chromatic violet blue. The natural ultramarine is only slightly violet, the artificial is very much so. Also called lazulite-blue.
    • n ultramarine Azure-stone.
    • ultramarine Situated or being beyond the sea.
