About Sodalite - History and Introduction
Sodalite is typically a deep blue mineral that gets its name from its sodium content. A sodalite deposit was discovered in Greenland in 1806 and then sodalite ornaments were seen in 1891, when larger deposits of gem-quality material were found in Ontario, Canada. Apart from blue, sodalite can be gray, yellow, orange or pink. However, for gemstone use, sodalite is typically blue, and often has white veins running through it. Sodalite is also sometimes sold as "alomite", "blue stone" and "ditroite".
A pink variety of sodalite is called hackmanite. This purple or pink gemstone was found in gem-quality deposits in 1991, in Quebec. Hackmanite exhibits the rare gemstone phenomenon of tenebrescence (also known as reversible photochromism), which means that it changes color when exposed to sunlight, and the process is reversed when the light changes.
Sodalite can be identified by its deep blue color and strong orange fluorescence. It can sometimes exhibit a violet tint and in opaque form often has white veins or patches running through it, which are composed of calcite. Sodalite is rare in transparent crystal form and can be gray, yellow, orange, blue, violet or colorless.
Sodalite is found in Brazil (Bahia), Greenland, India, Canada (Ontario), Namibia, Russia (the Urals) and the USA (Montana).

Sodalite Color
Sodalite can be gray, yellow, orange or pink. However, for gemstone use, sodalite is typically a deep blue color, similar to the color of lapis lazuli, and often has white veins or patches running through it.
Sodalite Clarity and Luster
Sodalite tends to exhibit a vitreous luster with a greasy luster on fractures. It is transparent to opaque, and can be interspersed with white calcite inclusions that appear like veins or patches.
Sodalite Cut and Shape
Opaque sodalite tends to be cut en cabochon. It can be cut into ovals, baguettes, rounds or fancy shapes. Transparent material is faceted, and is quite rare.
Sodalite Treatment
Synthetic sodalite has been available since 1975, and is also known as "basic sodalite". Natural sodalite is also widely available and all reputable gem traders declare any synthetic or treated material.

A violet-pink tenebrescent variety of sodalite is known as hackmanite. Sodalite can also be found in transparent, colorless form. Transparent sodalight is very rare as most sodalite gemstones are violet-blue and opaque. Lapis lazuli is similar in appearance to sodalite, and lapis can even include sodalite as a consituent. Owed to similaries, sodalite can easily be mistaken for lapis lazuli. However, lapis lazuli has a higher specific gravity (density), ranging from 2.5 to 3. Moreover, lapis lazuli is technically defined as a rock, whereas sodalite is a pure mineral by itself.
Sodalite can also be mistaken for blue azurite (also called chessylite) because of its similar blue azure color. However, azurite has a lower hardness rating based on Mohs scale of mineral hardness, ranging from only 3.5 to 4, and azurite is composed of basic copper carbonate. Dumortierite is also similar to sodalite in color, but has a higher Mohs hardness of 7 (up to 8.5 in aggregate form). Lazulite has a similar color and hardness to sodalite, but lacks the fluorescence of sodalite.

Sodalite is a fairly versatile gemstone that can be used in a variety of gemstone jewelry designs. Sodalite beads are popular in beaded necklaces, earrings, and bracelets. Beads can be spherical, tubular, square or tumbled. Sodalite also makes attractive cabochon pendants, rings and earrings. Sodalite can be set in silver, gold or copper. It can be wire-wrapped or used in tribal-style jewelry. Sodalite looks stunning by itself or teamed with white gemstones, such as pearls, quartz or topaz. Since sodalite is rather soft, care should always be taken when wearing sodalite gemstone jewelry, particularly when wearing sodalite rings.
Note: Buy colored gemstones by size and not by carat weight. Colored stones vary in size-to-weight ratio. Some stones are larger and others are smaller than diamonds by weight in comparison.

Sodalite Gemstone Jewelry Care and Cleaning Back to Top
 Sodalite is considered to be fairy tough, but it is also fairly soft at 5.5 to 6 on the Mohs scale. It's softer than many gemstones, but with care, jewelry and ornaments can last for many generations. Sodalite can be quite sensitive to strong pressure, high temperatures and harsh household chemicals and cleaners. Avoid exposing sodalite to bleach or sulphuric acid. Most sodalite can be cleaned using warm, soapy water, but some dyed materials may not be stable. For dyed or impregnated stones, it's best to test a small area first to ensure stability. Wipe down stones using only a soft cloth and be sure to rinse well to remove any soapy residue.
Always remove any sodalite gems or jewelry before exercising, playing sports or engaging in vigorous household chores. When storing your sodalite gemstones, store them separately from other gems and jewelry to prevent scratches and fractures. It is best to wrap your stones using a soft cloth and place them into a fabric-lined jewelry box for extra protection.
