Collection: Blue Cambrian Clay

Clays & Minerals

Illite / Smectite — Cambrian deposit

Blue Cambrian clay is one of the rarest and most ancient cosmetic clays in the world, sourced from deposits in Siberia that formed during the Cambrian period, over 500 million years ago. Its striking blue-grey color comes from its exceptional mineral density, particularly its high silver content, which gives it natural antimicrobial properties found in few other clays. It has been used in Russian and Eastern European spa traditions for generations.

In our soap and solid haircare formulas, Blue Cambrian clay produces distinctive blue-grey tones that are unlike any other natural colorant, a color that speaks to the deep geological history of the ingredient and creates a soap that is visually striking and immediately recognizable.

How It Works

Blue Cambrian clay's high mineral content, including silver, silica, potassium, and magnesium, provides meaningful skin-supportive benefits alongside its cleansing action. Its natural silver content contributes antimicrobial properties, while its fine smectite particles provide gentle but effective absorbency. It is suitable for most skin types and imparts a clean, mineral character to finished formulas.
