Tourmaline is a wonderful gemstone within the vast universe of precious stones. Tourmaline is especially famous for its amazing color variety and unusual crystal structure and diversity. There are bright green, pink tourmalines, as well as black, blue, red, and colorful tourmalines.

Contrary to other gemstones that are mainly appreciated due to their unique color, tourmaline can have many different colors. Moreover, some crystals have the combination of two or even more colors in one stone.

However, tourmaline gemstones are not only diverse and interesting in their colors. The mineral content, hardness, clarity, source, cut, carat weight, and natural properties make it unique.

This complete guide unveils what tourmaline is, how tourmaline gemstone is formed in nature, its varieties, main colors, hardness, source, quality factors, jewelry uses, and what to look for in tourmaline gemstone.

What is Tourmaline?

Tourmaline is a family of minerals that occur in nature in diverse crystalline forms and colors. Not only is tourmaline used as a mineral, but it can also be used as a gemstone. Clear and attractive crystals of tourmaline are cut into facets for making jewelry.

One of the characteristics of tourmaline gemstones is their colorful diversity. The color range of tourmaline can be from black and brown to green, pink, blue, red, yellow, orange, and many more depending on the mineral composition.

Natural tourmaline can be found as:

• Rough mineral crystals

• Polished gemstones

• Faceted gemstones

• Cabochons

• Mineral specimens

• Loose gemstones for jewelry

This diversity makes tourmaline appealing to both gemstone collectors and people looking for distinctive stones for custom jewelry.

How Does Natural Tourmaline Form?

Naturally formed tourmaline is formed through geological processes that take a long time to complete. It may be found in different geological environments where there is fluid-rock interaction in the process of creating and modifying the Earth’s crust. The chemistry and the conditions of its formation will determine its:

• Color

• Transparency

• Crystal shape

• Internal characteristics

• Chemical composition

• Overall appearance

One reason for this difference in appearance of natural tourmaline gemstones is the geological differences which exist. Inclusions and variations may also be present in tourmaline gemstones. These do not automatically mean that the gemstone is inferior; rather, they can tell us about the origin of the gemstone.

Why Is Tourmaline So Popular?

The popularity of tourmaline comes largely from its versatility. A single gemstone family can offer:

• Bright pink gemstones

• Rich green gemstones

• Deep blue varieties

• Vivid red and purple tones

• Dark black crystals

• Rare multicolored stones

• Distinctive watermelon patterns

It is therefore possible to find tourmaline that suits very diverse tastes and styles. Another advantage is that tourmaline is available in a wide variety of sizes and qualities. Some are perfect for use in jewelry, while others are unique enough for collectors of minerals.

Tourmaline Colors

Color is one of the most recognizable characteristics of tourmaline. The gemstone is famous for its broad natural color range and, in some cases, multiple colors appearing within a single crystal. Common tourmaline colors include:

• Green

• Pink

• Blue

• Black

• Red

• Yellow

• Orange

• Purple

• Brown

• Multicolor

Some stones can display gradual or distinct transitions between colors. These unusual combinations are part of what makes tourmaline particularly interesting to collectors.

Types of Tourmaline

Tourmaline consists of several varieties and mineral species. Gem quality tourmaline is frequently named after the variety according to its color, composition, or special features. Some of the most common tourmaline varieties include:

Elbaite Tourmaline

Elbaite is one of the most important species of tourmaline in the gemstone market. It includes many colorful varieties of tourmaline that are used in jewelry. Gem-quality pink, green, blue, and multicolor tourmalines belong to this variety.

Schorl Tourmaline

Schorl is usually black and is one of the most common varieties of tourmaline. It is highly appreciated as a mineral specimen and is associated with black tourmaline in the gemstone and crystal market.

Dravite Tourmaline

Dravite is usually connected with brown and dark-colored tourmalines and is another important variety of tourmaline mineral.

Rubellite

Rubellite is the name of attractive red and pink-red tourmaline.

Indicolite

Indicolite is the blue variety of tourmaline. Its color can be light blue, deep blue, or blue-green.

Paraiba Tourmaline

Paraiba tourmaline is distinguished with its bright blue, greenish-blue or neon-like colors. It became one of the most famous varieties of tourmaline due to its rarity and special appearance.

Chrome Tourmaline

Chrome tourmaline is distinguished with its intense green

Tourmaline Hardness and Durability

The hardness of tourmaline is one of the essential factors when choosing the gemstone for jewelry. The hardness of tourmaline lies approximately between 7 and 7.5 points on the Mohs scale, providing good scratch-resistance compared to many other softer gems.

Nevertheless, there are several more aspects to keep in mind when choosing the gemstone for daily wear. While choosing tourmaline for jewelry, also pay attention to:

• Structure of crystals

• Inclusions

• Cutting

• Setting

• Exposure to blows

• Type of jewelry

A properly selected and well-protected piece of tourmaline jewelry can be worn in rings, earrings, necklaces, and other types of jewelry. If you wear your ring all the time, a proper cut and setting can decrease the chances of breakage.

Tourmaline Clarity and Inclusions

Tourmaline, like other natural gemstones, can have inclusions inside the stone. The term clarity relates to how clear and visually clean the gemstone is, as well as if there are any visible internal features. Inclusions can influence the following factors in a specific type of tourmaline:

• Transparency

• Brilliance

• Appeal

• Rarity

• Market value

Nevertheless, clarity needs to be evaluated in conjunction with the type of tourmaline. Rare color with slight inclusions can be very valuable, whereas transparent stone with a beautiful cut can be interesting too. Natural inclusions can serve as one of the ways of distinguishing a natural gemstone from synthetic or imitation stones.

Tourmaline Cut and Shape

The cut of a tourmaline gemstone influences how the stone interacts with light and how its color is displayed. Common shapes include:

• Oval

• Round

• Cushion

• Emerald

• Pear

• Marquise

• Rectangle

• Octagon

The best cut depends on the rough crystal, color distribution, clarity, and intended use. For example, a cutter may choose a particular orientation to maximize the visible color or preserve valuable material from an unusual rough crystal. This is particularly important for tourmaline because some crystals contain distinct color zones that can change depending on how the rough material is cut.

Tourmaline Carat Weight

Tourmaline is available in many different sizes, from small accent stones to impressive collector-quality gems. Carat weight is an important part of gemstone pricing, but it should not be considered alone. Two tourmaline gemstones with the same carat weight can have very different values because of differences in:

• Color

• Clarity

• Cut

• Origin

• Variety

• Rarity

• Treatment

• Overall quality

For this reason, tourmaline value depends on the complete combination of characteristics rather than weight alone.

Where Is Tourmaline Found?

Tourmaline occurs in many parts of the world, and different locations are associated with different varieties and appearances. Important tourmaline-producing regions include:

• Pakistan

• Afghanistan

• Brazil

• Mozambique

• Madagascar

• Nigeria

• United States

• Other mineral-rich regions

Pakistan and Afghanistan are particularly interesting sources for gemstone enthusiasts because the region is known for producing attractive varieties of colorful tourmaline. Origin can be an important part of a gemstone's story, especially when a particular mining locality becomes associated with desirable material.

For more information about geographic sources and mining regions, explore our upcoming guide to where tourmaline is found and its major origins.

Pakistani Tourmaline

Pakistan is also one of the countries that provide natural colored gemstones such as tourmaline. Tourmaline produced from Pakistan is valuable because of the variation in its color and form. Natural tourmaline collected from the mountains of the country has more value due to its unique nature and geological composition.

As far as buying gemstone, origin may also be considered valuable but also alongside other factors such as color, clarity, cut and carat.

Afghan Tourmaline

Another country that produces natural gems is Afghanistan. Tourmaline from Afghanistan might present some beautiful colors and crystal form that would please both jewelers and collectors. As always happens with origin of a gemstone, the country it comes from cannot be seen as the only way to value it. The qualities of the gemstone itself should be taken into account.

Tourmaline Value: What Makes a Tourmaline Valuable?

Value of tourmaline may greatly differ depending on various criteria. Some of the main criteria for evaluating the value of a tourmaline stone include:

Color

In case of colored tourmaline color is one of the major factors that play an essential role in determining its value. Good and saturated colors make the stone more desirable.

• Overall craftsmanship

This makes direct price comparisons between different tourmaline gemstones difficult unless their characteristics are reasonably similar.

Natural Tourmaline vs Synthetic and Imitation Stones

When buying tourmaline, it is useful to understand the difference between natural, synthetic, and imitation materials.

• Natural tourmaline forms through geological processes in nature.

• Synthetic gemstones are produced in laboratory environments and are intended to replicate certain characteristics of natural gemstones.

• Imitation materials are different substances designed to resemble the appearance of another gemstone.

If the natural origin of a valuable tourmaline is important to you, ask the seller for clear information about the gemstone and, where appropriate, an independent laboratory report.

Tourmaline for Jewelry

Tourmaline is widely used in jewelry because of its broad color selection and attractive appearance. Popular applications include:

• Tourmaline rings

• Tourmaline earrings

• Tourmaline necklaces

• Tourmaline pendants

• Tourmaline bracelets

• Custom gemstone jewelry

One of the advantages of buying a loose tourmaline gemstone is the ability to select the exact stone based on color, shape, size, carat weight, clarity, and intended jewelry design. A loose stone can then be set into a custom ring, pendant, pair of earrings, or another piece of jewelry.

How to Choose a Natural Tourmaline Gemstone
