Sodalite Beads
Sodalite beads are a sodium aluminum silicate with chlorine, royal to navy blue with white veins. This collection holds every sodalite we stock: blue sodalite, white-flecked snowflake sodalite, orange sodalite and sodalite syenite, in a range of finishes and shapes for bracelets, necklaces and earrings.
Appearance
Blue sodalite ranges from a deep royal blue to an inky navy, veined and patched with white calcite and feldspar; strands vary from nearly solid blue to heavily marbled. Snowflake sodalite carries much more white, so the blue appears as islands in a pale ground. Orange sodalite is a sodalite-bearing rock in which orange and pink feldspar dominate, with blue patches scattered through it. Sodalite syenite is the host rock itself, grey and white with blue sodalite grains, and the sodalite in it glows orange under long-wave ultraviolet light.
A polished finish gives the blue a glassy depth and sharpens the white veins; a matte finish turns sodalite a soft denim. Faceting is uncommon on an opaque stone. At 5.5 to 6 on the Mohs scale, sodalite is a little softer than quartz: it wears well in everyday bracelets but will pick up fine scratches over the years if strung directly against harder stones.
Formation and origin
Sodalite crystallizes in silica-poor igneous rocks, nepheline syenites above all, where there was too little silica to form feldspar from all the sodium and aluminum present. The blue comes from sulfur-based color centers in the crystal structure, the same chemistry that colors the lazurite in lapis lazuli. Sodalite is darker and duller than lapis and almost never carries lapis's golden pyrite, which is the quickest way to tell them apart. Major sources are Bahia in Brazil, the Bancroft district of Ontario, Namibia and Bolivia. Fluorescent sodalite syenite from the Lake Superior shore is sold under a trademarked name.
Pairings
Crazy lace agate beads: warm cream, red and grey swirls against navy blue, a contrast that stays earthy rather than loud.
Unakite beads: pink feldspar and green epidote beside blue sodalite, two patterned stones close in hardness.
Ruby zoisite beads: green, red and black against sodalite blue, both opaque, mottled rocks that polish to a similar gloss.
Meaning and Metaphysical Beliefs
Sodalite meaning in crystal traditions centers on logic, truth and clear thinking, and it is often described as a stone for writers and speakers. Its blue places it with the throat chakra, and sometimes the third eye. It has little ancient history under its own name, having been identified only in the 19th century. These are traditional beliefs, not claims of physical effect.
