Sodalite (/ˈsoʊ.dəˌlaɪt/ SOH-də-lyte) is a tectosilicate mineral with the formula Na

₂, with royal blue varieties widely used as an ornamental gemstone. Although massive sodalite samples are opaque, crystals are usually transparent to translucent. Sodalite is a member of the sodalite group with hauyne, nosean, lazurite and tugtupite.

The people of the Caral culture traded for sodalite from the Collao altiplano. First discovered by Europeans in 1811 in the Ilimaussaq intrusive complex in Greenland, sodalite did not become widely important as an ornamental stone until 1891 when vast deposits of fine material were discovered in Ontario, Canada.

The national flag of the Philippines (Filipino: Pambansang Watawat ng Pilipinas) is a horizontal bicolor flag with equal bands of royal blue and crimson red, with a white, equilateral chevron at the hoist. In the center of the triangle is a golden-yellow sun with eight primary rays, to represent the original eight provinces that rebelled against the Spanish during the 1896 Philippine Revolution. At each vertex of the triangle is a five-pointed, golden-yellow star, each of which representing one of the country's three main island groups—Luzon, Visayas (though originally referring to the island of Panay), and Mindanao. The white triangle at the hoist represents liberty, equality, and fraternity. A unique feature of this flag is its usage to indicate a state of war if it is displayed with the red side on top, which is effectively achieved by flipping the flag upside-down.
