Tourmaline: A Rainbow Gemstone with a Colorful Past

Tourmaline, a dazzling gemstone prized for its incredible range of colors, has captivated people for centuries. But this gem is more than just pretty; it boasts unique properties and a rich history that adds to its allure. Let's delve into the world of tourmaline, exploring its science, history, and why it deserves a spot in your gem knowledge vault!

What is Tourmaline?

Tourmaline isn't just one specific gemstone, but a whole family of silicate minerals! Imagine a group of minerals sharing a similar structure, like a big family with different colored hair. In the case of tourmaline, the key ingredient is boron, an element that teams up with aluminum (aluminium), iron, and other elements to create a dazzling array of colors. This unique combination gives tourmaline a hardness of 7-7,5 on Mohs scale, making it durable enough for everyday wear in jewelry.

A Rainbow of Colors:

One of the most fascinating things about tourmaline is its mind-boggling color range. Unlike most gemstones with a limited palette, tourmaline can come in almost any color imaginable! Here are some of the most popular varieties:

• Rubellite: A fiery red variety, often mistaken for a ruby.

• Verdelite: A vibrant green, sometimes referred to as "Brazilian Emerald."

• Indicolite: A stunning blue, reminiscent of the summer sky.

• Paraiba Tourmaline: An electrifying neon blue, one of the rarest and most valuable tourmalines.

• Watermelon Tourmaline: A captivating gem with a pink core fading to a green rind, resembling a slice of watermelon.

• Black Tourmaline: Also known as Schorl, this variety offers a touch of elegance and is often used in protective jewelry.

Etymology: A Journey Through Languages

The name "tourmaline" has a fascinating journey through languages. It's believed to originate from the Sinhalese word "tōramalli," which referred to a group of gemstones including carnelian. As tourmaline traveled the trade routes, the name morphed into different versions adopted by European languages. The Portuguese used "turmali," and eventually, it landed on the "tourmaline" we know today (2023).

A History Fit for a Gem:

Tourmaline boasts a rich history that stretches back centuries. Here are some interesting highlights:

• Ancient Discoveries: Evidence suggests tourmaline use in jewelry as early as 300 BC in Sri Lanka and later in ancient Egypt.

• The California Gold Rush: Believe it or not, the California Gold Rush of the 1800s played a role in tourmaline's popularity. Miners mistook black tourmaline for emeralds, leading to a surge in tourmaline mining and appreciation for its true beauty.

• The Rise of Paraiba: In the 1980s, the discovery of vibrant blue tourmaline in Brazil, known as Paraiba tourmaline, sent shockwaves through the gem world. Its rarity and electric color made it a highly sought-after gem.

Beyond Beauty:  Unique Properties of Tourmaline

Tourmaline doesn't just impress with its looks; it has some unique physical properties too!

• Piezoelectricity: Certain tourmaline varieties can generate electricity when pressure is applied. This property is being explored for use in various technological applications.

• Pyroelectricity: Some tourmalines produce an electric current when heated. This phenomenon is still being researched, but it holds potential for future innovations.
