Nestled in the rugged beauty of the Canadian Shield, Bancroft, Ontario, is a hidden treasure for rockhounds and geology lovers. But among its hundreds of mineral varieties, one stands out—not just for its striking blue hue, but for the royal attention it once received. That mineral is sodalite, and its story is as rich as its colour.

A Gem Fit for Royalty

In 1901, during a Canadian tour, the Duke and Duchess of Cornwall (who would later become King George V and Queen Mary) were presented with a striking specimen of Bancroft sodalite. With its deep royal blue color, streaked with white veining and known to glow a fiery orange under ultraviolet light, the stone captured their imagination.

So much so, in fact, that they requested more of the beautiful mineral to be quarried and shipped to England, where it was used to decorate the interiors of Marlborough House—a royal residence in London. From that moment, Bancroft sodalite was no longer just a local curiosity—it had become a stone of kings and queens.

The Princess Sodalite Mine

The original source of this royal gem? The Princess Sodalite Mine, located just south of Bancroft. The mine was named in honour of this regal connection, and it remains one of the most accessible and popular collecting sites in the area. Visitors can tour the site, learn about sodalite’s history, and even dig their own specimens straight from the source.

Today, the mine welcomes everyone from amateur rockhounds to seasoned collectors—and every piece of sodalite pulled from the ground carries a little piece of that royal legacy.

What Makes Sodalite So Special?

Sodalite is a member of the feldspathoid group of minerals and is most commonly recognized for its rich, lapis-like blue color, though it can also appear gray, yellow, green, or pink depending on its chemical composition. But what really sets Bancroft sodalite apart is its fluorescent quality—under UV light, it glows in stunning shades of orange and red, making it a favourite among collectors.

Beyond its beauty, sodalite is believed by some to carry calming properties, associated with logic, clarity, and communication.
