Opal
The term "opal" refers to three different types of stones with considerably different physical properties: the iridescent precious opals, also known as noble opals, which are the most well-known; fire opals, which are vermilion red; and common opals.
Where does the word "Opal" come from?
The word "opal" comes from the Sanskrit word "upala" which means "precious stone."
What colors does Opal come in?
Opals can be any color.
Precious opals, also known as noble opals, are characterized by their iridescence, meaning the play of colors that changes depending on the viewing angle. This optical phenomenon is also called "opal fire."
Common opals, conversely, do not have this play of color.
Finally, fire opals are not iridescent like common opals, but their distinctive feature is their orange color, which can lean towards red.
It is worth noting that there is a type of black opal, very rare and sought after, which is more expensive than diamonds of equal carat weight.
What is its symbolism?
Today, opal symbolizes docility, sublimation, and perseverance, as well as October births (like tourmaline) and the 21st wedding anniversary.
Where does it come from?
Most opals are mined in Australia, but significant deposits can also be found in Ethiopia, Brazil, Mexico, and the United States.
How to care for my opal-set jewelry?
Opal is a very fragile stone with a very high water content. Some stones can break in case of dehydration and high heat.
It is recommended to leave your opal on a cotton pad soaked in water from time to time to hydrate it.
