Tourmaline (What is it? Formation and Where to Buy)
Share
Tourmaline is one of the most fascinating and diverse gemstones in the world. Its wide colour range and rich history make it a favourite for collectors, jewellers, and crystal enthusiasts. But many people who hear about tourmaline stones often wonder: What exactly is tourmaline, how is it formed, and is it worth having? This guide will answer all your questions and help you decide whether to add this unique stone to your life.
What is Tourmaline?
Tourmaline is a crystalline boron silicate mineral that comes in a wide variety of colours, from deep black to vibrant pink, green, and even rainbow shades. Unlike many gemstones that have a limited palette, tourmaline is often called the “rainbow stone” because of its diversity.
It is also one of the most durable semi-precious stones, with a Mohs hardness rating of 7–7.5, making it suitable for everyday jewellery. Tourmaline is often associated with healing, balance, and protection, which has added to its popularity in spiritual and wellness communities.
How is Tourmaline Formed?

Tourmaline forms deep within the Earth through hydrothermal activity. This process occurs when hot water, rich in minerals, moves through cracks in rocks and cools slowly, allowing crystals to grow. Because of the unique environments where it develops, tourmaline stones often trap trace elements such as iron, magnesium, or lithium, which give them their wide range of colours.
The best deposits of tourmaline are found in Brazil, Afghanistan, Mozambique, Nigeria, and the United States (notably in California and Maine). Brazil alone supplies nearly 90% of the world’s gem-quality tourmaline, making it a central hub for the trade.
History of Tourmaline
The history of tourmaline goes back centuries. Ancient Egyptians believed tourmaline travelled through a rainbow on its way up from the earth, which is why it comes in so many colours. In the 18th century, it was brought to Europe, where it was prized as both a collector’s gem and a scientific curiosity.
Today, tourmaline remains one of the most popular semi-precious stones, used in jewellery, healing practices, and even in technology. Because of its piezoelectric properties, tourmaline can generate an electrical charge when heated or compressed, making it useful in pressure gauges and other instruments.
Is Tourmaline Worth Having?
Yes, tourmaline is worth having, both for its beauty and its durability. In terms of jewellery, it is less expensive than gemstones like sapphire or emerald but still provides stunning colour and brilliance. The average price for tourmaline ranges from £30 to £100 per carat, though rare varieties like Paraiba tourmaline can cost over £10,000 per carat due to their electric blue colour.
From a collector’s perspective, tourmaline offers incredible variety and accessibility. From an energy perspective, many believe it provides grounding, balance, and protection against negative energies, especially black tourmaline, which is one of the most sought-after types in metaphysical circles.
