Jewelry Made With Opal Stones Proves Exceedingly Popular
Opal stones are uniquely beautiful, eye-catching gems that come in a wide variety of colors. What truly sets opals apart from other precious stones is their ability to change color depending on the angle at which they are viewed. Exquisite gem-quality opal is scarcer than emeralds and rubies. Their rarity is what makes these stones exceedingly popular for use in elegant jewelry pieces.
From Down Under
Over 90% of the world’s opals are mined in Australia, and they are the country’s national gemstone. Some major Australian opal mines are located in Coober Pedy, Andamooka, and Lighting Ridge. Opal stones are not found in concentrations like diamonds and other gems, but are typically scattered in small patches over many miles.
Types of Opals
Black opal is the rarest and most prized off all types of opals, and may incorporate a full rainbow of brilliant colors on a black background. Boulder opal is mined from thin veins in ironstone boulders. It can be a solid color or have flecks of different colors. Light opal may contain many swirls of color, and typically has a light blue or white background.
High Water Content
Opals have some of the highest water content of any gemstone. They can contain up to 10% water based on their weight. Even though their water content is high, they are still relatively strong and not prone to cracking.
