Dumortierite
Dumortierite — named in 1881 for the French paleontologist Eugène Dumortier — is a rare aluminum borosilicate found in deep denim blue to violet. Sometimes described as "solidified water" for its watery depths, it grows in coarse, fibrous masses that polish into velvety blue stones, occasionally threaded through quartz. Sources include Brazil, Madagascar, and the United States.

What Is Dumortierite Good For?
Dumortierite is known as a stone of patience. Linked to the throat and third-eye chakras, it is traditionally used to steady a restless mind, encourage disciplined thinking, and support clear, honest communication. Many value it for easing stubbornness — one's own as much as others' — and for bringing a calm, organized energy to study, planning, and detail work.
How to Use Dumortierite
- Wear it daily — The rings in this collection keep its steadying blue close at hand.
- For study & planning — Keep a piece on the desk as a traditional companion for focus and follow-through.
- For communication — Stones worn near the throat are the classic choice; a ring kept in sight works as a quiet reminder.
- For calm — Hold a piece and breathe slowly when the mind races.
Care & Cleansing
- Rates 7 on the Mohs scale; durable for everyday wear.
- Wipe with a soft, damp cloth and dry afterwards.
- Cleansing: rest it overnight on a Clear Quartz cluster — the simplest daily reset. For a deeper cleanse, try our Herkimer Diamond water method: soak a Herkimer Diamond in water for a few hours, then rest your crystal in the water for 10–30 minutes. Moonlight around the full moon is a good tool-free alternative. Read our full cleansing guide.
- Avoid salt water — some shops recommend it as a cleansing method, but salt can permanently dull or damage the surface.
