I'm so excited our new product will soon be available to order. One of the stone varieties available in the new kit will be 8mm round sodalite stones. As such, I thought now would be as good a time as any to take a bit of a deeper look at this stone.

Sodalite is a captivating gemstone that has been cherished for centuries for its stunning blue hues and remarkable metaphysical properties. With a rich history, intriguing formation process, unique qualities, and diverse uses, sodalite continues to captivate the hearts and minds of people around the world. In this blog entry, we'll delve into the fascinating world of sodalite, exploring its origins, characteristics, and the myriad ways it is valued and utilized.

Formation of Sodalite

Sodalite is a mineral that forms within igneous rocks, typically in association with other minerals like nepheline and cancrinite. Its formation is a complex process that involves the interaction of sodium-rich fluids with rocks containing aluminium and silica.

The distinctive blue colour of sodalite comes from the presence of sulphur compounds, while the white streaks and spots are usually due to calcite or nepheline. The exact conditions required for sodalite formation are relatively rare, which makes sodalite a somewhat uncommon gemstone.

Qualities of Sodalite

Sodalite is known for its beautiful deep blue colour, often exhibiting variations from light blue to violet-blue. It has a vitreous to greasy lustre and is transparent to translucent. The stone is typically found in massive or granular forms, making it suitable for carving and cabochon cutting.

One of the most intriguing qualities of sodalite is its ability to fluoresce under ultraviolet light, a feature that enhances its appeal and mystique. Its Mohs hardness rating of 5.5 to 6.0 makes it relatively durable, but care should be taken to protect it from scratches and harsh chemicals.
