Tourmaline is known for its bi-color and tri-color varieties, where multiple colors are present within a single crystal. These gems can display striking combinations of colors, adding to their allure and value.

The Science Behind Tourmaline’s Colors

The stunning variety of colors found in tourmaline can be attributed to the presence of various elements and their interaction with the crystal structure. Different trace elements, such as iron, manganese, and lithium, can influence the coloration of tourmaline. Additionally, the arrangement of these elements within the crystal lattice can lead to variations in color intensity and hue.

For example, pink tourmaline owes its color to manganese, while green tourmaline’s color comes from iron and sometimes vanadium. The neon-blue and neon-green hues of Paraíba tourmaline are the result of copper and manganese.

Examine the gemstone for inclusions and imperfections. While some tourmalines are naturally included, look for stones with good transparency and minimal visible flaws.

3. Cut:

The cut of a tourmaline can significantly affect its beauty. Well-cut stones showcase their color and brilliance to the fullest.

4. Carat Weight:

Tourmalines come in a wide range of sizes, from small accent stones to larger focal points. Choose a size that suits your jewelry design or personal preference.

5. Origin:

Some tourmaline varieties, such as Paraíba tourmaline, are highly valued for their specific geographic origins. Consider whether the origin is important to you.
