October Birthstone: Opal & Tourmaline Etymology, History, and Folklore


There are two origins of opal, one’s from the Sanskrit, and the others from the Greek. From the Sanskrit word “upala” which means precious stone, Romans believe that it is the most powerful amongst all gemstones. They called it “opalus” because it contains all the colors of gemstones.

For Greeks, there’s an argument between the origins of the opal. Some prefer the word “opallios”, meaning, to see a change of color or the opal’s iridescence. On the contrary, other Greeks used the word “paederos” that has the meaning of precious stones. They refuse to use “opalus” because they believed it came to Roman who invaded their lands.

Due to its rare features, Romans used opal to show authority in society and thought that this gem is the most expensive and powerful stone. The first known relics of opals were found in Kenya and geologists believed that it originates from Ethiopia. Thousands of years later, Ethiopian opals were exposed and introduced to the market.

In medieval times, opals are believed to cure eye disease, boost the immune system, and empower the mind. Ancient women wear opal jewelry such as necklaces to prevent their blond hair from darkening or fading. They even though that using opal can make anyone invisible if they wish, which they called Patronus.

From the myths of the Native Australian, it is said that the Creator came down to Earth through the rainbow to share peace with humankind. The ground where his foot touched, opals came to life shining in different colors. For Arabs, opals are magic stones that came from lighting then fall during thunderstorms.

When Zeus defeated the titans, his tears of joy turned into opals as believed in Greek mythology. As for Aztecs, Fire Opal is renowned as the Stone of the Bird Paradise which could restore the cycle of creation and destruction. However, some legends claimed that opal brings bad luck and considered an evil stone.


Spanish and Portuguese discovered green and blue tourmaline in the 16th century while looking for gold. They mistook it as emerald and sapphire and so traders find ways to differentiate these stones. Using a Sri Lankan word “turmali’ meaning “mixed gems”, they used it to refer to crystal gems found on the island of Ceylon.

Dutch traders began to import tourmalines to Europe in the 1600s as the demand for these stones started to increase. In the year 193, tourmaline was popular in the United States, particularly in Maine and California until it was recognized as an American gemstone. However, despite its growing fame, China became the main source of tourmaline in the 19th century.

But in half of the 20th century, miners discovered large tourmaline deposits in Brazil. The demand dramatically expanded until tourmaline mines appear almost all around the world. In the 1950s, fine tourmalines were produced in Madagascar, Tanzania, Russia, Pakistan, and Afghanistan.

For centuries, many cultures had different beliefs about the power of tourmalines. In ancient India, they used tourmaline as a tool to help them see good things. And today, this gemstone serves as a charm to protect people from any cause of danger.
