Tourmaline is one of the most fascinating gemstones in the world, admired for its wide variety of colours and unique character. For buyers, the challenge often lies in understanding what tourmaline is, how much it costs, and which type is the best to invest in or wear. This guide will break everything down simply and clearly, so that by the end, you will know exactly what to look for when buying tourmaline stones.
What is Tourmaline?
Tourmaline is a semi-precious gemstone that comes in more colours than almost any other stone. Unlike diamonds, which are mostly colourless, or emeralds, which are always green, tourmaline can be pink, green, blue, red, yellow, or even a combination of colours. One of the most famous varieties is watermelon tourmaline, which is pink in the middle and green on the outside, resembling a slice of watermelon.
On the Mohs hardness scale, tourmaline ranks between 7 and 7.5, making it durable enough for jewellery but still needing careful handling to prevent scratches. Its versatility and strength have made it increasingly popular for both everyday wear and fine jewellery.
Where is Tourmaline Found?
Tourmaline is mined across the globe, with some regions producing especially sought-after varieties:
-
Brazil is the largest source of tourmaline, known particularly for Paraiba tourmaline, which glows with neon blue and green hues.
-
Africa (especially Mozambique, Nigeria, and Madagascar) has become a leader in producing rubellite (red) and indicolite (blue) stones.
-
Afghanistan and Pakistan are known for vibrant pink and green tourmaline.
-
The United States also mines tourmaline, with California and Maine producing pink and green varieties.
According to the Gemological Institute of America (GIA), tourmaline from Brazil and Mozambique is often the most valuable, with Paraiba stones reaching record-breaking prices at auction.
Where is Tourmaline Sold?
Tourmaline can be purchased in several ways, but not all options are equal in terms of quality and security.
-
Jewellery stores: Good for those who want finished rings, necklaces, or bracelets with certified tourmaline stones.
-
Online retailers: Websites like Blue Nile, James Allen, or Brilliant Earth offer high-quality, certified tourmaline.
-
Gem shows and markets: Great for collectors, but buyers need to be cautious as not all sellers provide certification.
-
Auction houses: Best for rare or investment-grade tourmaline.
When buying online or in-store, always ask for a certificate of authenticity from a trusted lab such as GIA or IGI. Without certification, you risk buying a treated or fake stone.
Factors Affecting the Price of Tourmaline
The price of tourmaline varies widely depending on several factors:
-
Colour: Bright and rare colours are the most expensive. Paraiba tourmaline, for example, can sell for £10,000 or more per carat, while more common green stones may cost under £100 per carat.
-
Clarity: Stones with fewer inclusions are valued higher.
-
Size: Larger tourmaline stones are rarer and command higher prices.
-
Cut: A well-cut stone shows better brilliance.
-
Origin: Stones from Mozambique and Brazil often fetch higher prices due to their quality and rarity.
The global gemstone market is growing rapidly. According to Statista, the coloured gemstone market, including tourmaline, is expected to exceed £9 billion by 2030, showing a strong demand for stones like tourmaline.
Types of Tourmaline and Which is Best to Buy?
Tourmaline is not a single stone but a group of minerals. The most popular types include:
-
Paraiba Tourmaline: Neon blue or green; the rarest and most expensive variety.
-
Rubellite Tourmaline: Bright pink to red stones that are highly desirable.
-
Indicolite Tourmaline: Shades of blue that are elegant and rare.
-
Green Tourmaline: Abundant but still attractive and affordable.
-
Watermelon Tourmaline: Dual-coloured, often used in unique jewellery designs.
-
Black Tourmaline (Schorl): Common and often worn for spiritual or protective reasons.
If you want a gemstone for investment, Paraiba or Rubellite are smart choices. For everyday wear, green or watermelon tourmaline offers beauty without the high price tag.
