Dumortierite: A Gemstone with a Story

If you've ever stumbled upon a beautiful gemstone with a deep, mysterious blue hue, there's a chance you were looking at dumortierite. This fascinating mineral has a unique story, rich in both scientific and historical significance. Let's dive into the world of dumortierite and uncover its secrets.

What is Dumortierite?

Dumortierite is a relatively rare mineral that belongs to the family of aluminum (aluminium) boro-silicate minerals. Let's break down what that means:

• Aluminum (Aluminium): A lightweight, silvery-white metal.

• Boron: A chemical element often used in things like laundry detergents and eye drops.

• Silicate: A group of minerals that form a major part of the Earth's crust, with silicon and oxygen being their main ingredients.

The specific chemical formula of dumortierite is Al₇BO₃(SiO₄)₃O₃. Its color is its primary allure, usually a stunning deep blue to violet, though you might find shades of brown, green, and even pink! The crystals within dumortierite are fibrous and tend to form in long, slender shapes.

Word Play: The Name Behind the Gem

Like many things in science, dumortierite wasn't always called that. The name "dumortierite" is actually a tribute to a French scientist named Eugène Dumortier. Eugène was a paleontologist, meaning he studied fossils to understand ancient life. Back in 1881, dumortierite was discovered in France and his name was attached to the newly found mineral.

Where Can You Find Dumortierite?

While not as common as some other gemstones, dumortierite isn't impossible to find. It's scattered across the globe, with deposits in countries like:

• Brazil

• Canada

• France

• Madagascar

• Sri Lanka

• United States

Dumortierite is generally found in rocks that have undergone a process called metamorphism. Metamorphism happens deep within the Earth, where extreme heat and pressure change existing rocks and minerals into new forms.

Dumortierite Through History

While dumortierite might not have the fame of diamonds or emeralds, it has quietly made its mark on history and various cultures. Here are some interesting tidbits:

• Industrial Uses: In the past, dumortierite has been used to make high-quality porcelain. Porcelain is a type of ceramic known for its smooth, white finish and durability.

• Not Just a Pretty Stone: People throughout history have believed that gemstones, including dumortierite, possess special properties or powers. Some associate dumortierite with enhanced intellect, patience, and a sense of order.

• Dumortierite Quartz: Have you heard of this variety? It's a type of quartz (a very common mineral) that has inclusions of dumortierite trapped inside. This creates a mesmerizing blue-speckled appearance within the clear or milky quartz.

Today (2023), the main draw of dumortierite is its beauty and its relative rarity. Let's see how this mineral is typically used:

• Jewelry: Those vibrant blue and violet colors make dumortierite a striking addition to jewelry pieces like necklaces, rings, and earrings. It's often cut into cabochons (smooth, polished stones) or beads to showcase its color.
