What Is The Verdelite Crystal?

Green tourmaline is a rare variety of tourmaline that is sought after by many gem collectors. It boasts different powerful abilities and properties that make it desirable for many people. It is said to be related to the heart chakra and symbolizes communication and self-love.

This crystal is a member of the borosilicates, minerals with alkaline or earthy chemistry that often occur alongside quartz gems. The name of this stone comes from its color, which is a beautiful grassy green hue. It also has some copper and aluminum in its chemical makeup.

Usambara Effect

The presence of Cr+3 ions in the crystalline structure gives green Tourmaline a unique property known as the “Usambara Effect.” This effect causes a change in the color of the gemstone depending on the path length that the light travels through the material.

In Verdelite, the color can change from green to red as the amount of light passing through it increases or decreases. The color green to olive green even if there is less light.

Usambara Effect Vs. Alexandrite Effect

A similar kind of color change is seen in Alexandrite stones, blue to red, when they are exposed to sunlight vs. incandescent light. While the presence of Chromium ions causes both phenomena, they are two distinct effects with different mechanisms.

Alexandrite stones change their color due to the absorption spectrum of the Chromium ions in the yellow region of the visible light spectrum.

On the other hand, the Usambara effect is caused by the positions of bands of absorption of Cr3+ ions, the light ratio, and the sample’s thickness.

Verdilite/Tourmaline Pronunciation

Tourmaline is pronounced tuor·muh·leen while Verdilite is pronounced Ver·duh·lite.

Tourmaline gets its name from the Sinhalese word for carnelian stones, “tōramalli.” 

Historical Significance

  1. Brightly colored Tourmaline gemstones were found in Ceylon (now Sri Lanka) and were brought to Europe by Dutch East India Company traders, becoming a widespread curiosity.
  2. Because of its pyroelectric properties, Tourmaline was sometimes called the “Ceylonese Sri Lankan Magnet” – it could attract and then repel hot ashes.
  3. In the 19th century, chemists used tourmalines to polarize light by shining rays onto a gem’s polished surface.

A type of Green Tourmaline, known as Watermelon Tourmaline, shows two colorations at once. The inside is pink while the outside is green, hence the name.

How To Tell If It Is Real?

Verdilite is a common gemstone, so most vendors will not substitute it with another gem. However, some scammers may make fake Green Tourmaline gems using colored plastics or glass.

You can identify whether a stone is genuine or not using the following criteria:

  1. Color Depth: Natural Green Tourmaline has a variable color scheme with varying hues. If the color of the Tourmaline crystal looks uniform and dull, it is not real. This type of coloration is an indication of dying.
  2. Scratch Test: Tourmaline is a hard mineral with a 7 – 7.5 on the Mohs hardness scale. Due to this property, it is tough to scratch this mineral. If you try to score the stone with a knife or any other sharp object, it should not leave any marks on the surface of the Tourmaline. If you can scratch it, then it is not real.
  3. Usambara Effect: You can verify the reality of your Green Tourmaline gemstones by checking for the Usambara effect. The thickest stone parts should be red, while the thinner parts should be green. If there is no color difference between the thick and thin parts, it is not a genuine Tourmaline crystal.
  4. Acetone Test: Take your gemstone and place it in an acetone bath for a few minutes. The dye will dissolve in the acetone, and the color will be removed from the stone. The gemstone is not genuine if you notice a stain in the acetone solution after a few minutes. Natural gemstones shouldn’t release color in acetone.
  5. Transparency: Coloring plastic or glass through artificial means makes them opaque. However, genuine Tourmaline gemstones are translucent or transparent. If you notice a colored Tourmaline gemstone that does not allow light to pass through it, it is most likely colored glass or plastic.

If you cannot verify whether your gemstone is natural or not, you should bring it to an expert. They will test it for you in various ways. For example, they may use a refractometer to test the gemstone’s optical properties. They will also use other tools like microscopes, polariscopes, and Hardness sets to test the physical properties of the gem and give a detailed result.

Green Tourmaline Stone Cost And Value

The value of a gemstone is defined by the four C’s. Experts use the four Cs to evaluate a gem’s worth: carat, cut, clarity, and color.


The size of the stone is a significant determinant of its value. Larger stones are rarer and, therefore, more valuable. Thus, the price increases exponentially with the size of the gemstone.


The cut of a gemstone is how it has been faceted and polished. A well-cut stone will reflect light better than one that is poorly cut. The gem’s cut is the most significant factor in determining the value of uncolored stones.

A well-cut stone with no flaws that reflects light in all the right ways will be much more expensive than a poorly cut one.


Clarity refers to the number of imperfections in a stone, its transparency, and how many inclusions are present within it. Not all stones with inclusions are worth less. Some gems, like the Dendritic Agate, derive most of their value from the pattern of the inclusions found within them.

However, the presence of even one inclusion can make the stone less valuable than other stones. A stone’s clarity is partially determined by its cut, so if you have a perfect stone that has been cut poorly, then it might be worth less than a stone with imperfections that is well-cut.


For non-transparent stones, color is the most critical factor in determining their price. The intensity, continuity, depth, and pattern of the color found on a gemstone influence its price.

The color of a stone is often what makes it so desirable, so if you have a bright blue sapphire or fiery red ruby, you’ve got yourself a valuable gem. The more intense the color is and the more consistent it is throughout the stone, the higher its value will be.

The most expensive colored gemstones are those with vivid and intense colors. For example, the world’s most expensive ruby is the Sunrise Ruby, which has a fierce orange-red shade that is very rare.

Some colors are considered rarer than others and are more valuable when found in gems. For example, the most expensive variety of Tourmaline is the “Paraiba Tourmaline,” which has a rare green and neon-blue color.

Price Per Carat

Green Tourmaline is a widely available and relatively cheap stone. You can find a gem for $7-30/Carat in the online marketplace. This is because it is a widespread stone and can be found in many locations around the world.

If you’re looking for something more unique, you might want to consider one of the other colored Tourmalines. For example, Pink Tourmaline has an average price of $50-100/Ct depending on its quality.
