Egyptian legend maintains that during its formation, Tourmaline passed over a rainbow as it made its journey from the Earth’s center which led to it assuming the seven colors of the rainbow. Tourmaline is mined in a vast array of colors; the widest range of colors of any gemstone in the gem kingdom with virtually every color represented, including black, bi-colors and tri-colors.


Tourmaline is its own gem species, with many different unique types. It forms in an incredible prismatic crystal habit, meaning that it forms in gorgeous long hexagonal 'pencils' within the host rock.

Tourmaline has many remarkable qualities but one of the most interesting physical attributes is that it has the ability to become magnetic under heat or pressure. When heat is applied to Tourmaline and becomes magnetic, it's known scientifically as Pryoelectric. Similarly, applying pressure to it achieves the same effect, Piezoelectric. 


The term Tourmaline is derived from the Sinhalese words 'tura mali' meaning 'a stone with mixed colors'. Being dichroic, Tourmaline also has the ability to subtly shift its color depending on the light source as it changes from natural to artificial.

There are many different names given to various colors of Tourmaline, some are official trade names and others are marketing ones.

Tourmaline has probably been used a gem for centuries, but it wasn't until modern mineralogy that it has been properly identified, they were likely to have been mistaken for other gemstones.

Tourmaline became known as an 'American Gem' in the late 1800's due to Tiffany & Co's gemologist George F. Kunz as he praised the pieces that were being found in the deposits of Maine and California.

The supply of Tourmaline began to expand during the first half of the twentieth century, when Brazil began to yielded some large deposits. Then, in the 1950's other countries around the world began to find other deposits.


A favorite among jewelry designers due to its amazing wide color range, durability, availability and affordability. Tourmaline can be made into all forms of jewelry and can be set in all jewelry metal types. Due to the huge range of colors and hues any number of color combinations and styles can be created and as with all gemstones, they look stunning set with Diamonds.
