Jasper, an aggregate of microgranularquartzand/orchalcedonyand other mineral phases, is an opaque, impure variety of silica, usually red, yellow, brown or green in color; and rarely blue. The common red color is due to iron(III)inclusions. The mineral aggregate breaks with a smooth surface and is used for ornamentation or as a gemstone.
Jasper is a stone of gentleness, comfort, and relaxation. Has protective energies and is sometimes called the "nurturing stone".
