Opal Essence: Know How Did They Evolve

Opal jewelry is truly unique. No two stones are the same and they have such complex bursts of color that it is often difficult to describe them.

Where do they come from?

Most of the pieces on the market come from Australia. The first mine White Cliffs started operating in the late 1800s. Other notable Australian mines are Andamooka, Lightening Ridge and Coober Peddy. More recently, deposits have been discovered in Central and South America, but Australia is still the most significant supplier.

Why is it so delicate?

These gems are known for their delicate nature. The reason for this is their chemical make-up. The stone in an (opal ring) is sedimentary. As silicate filled water passes through, it deposits the silicate and the gems grow from that in the nooks and crevices of river beds and caves.

The spheres of silicates are what cause the glorious diffraction of light in each stone. However, the water is what makes it so delicate. These jewelry-grade gems contain between 6 and 10% water while others may have as much as 20%. This makes them extremely soft.

How to care and clean them

As mentioned above, the stones in an (opal bracelet) are very delicate so care should be taken when wearing it. On the Mohs scale, these stones average about a 6 which means they can be chipped, scratched and broken quite easily. Instead of soaking, because it will absorb the liquid, simply wipe down the stones with a soft wet cloth. For storage, protect them from harder stones and make sure they have sufficient moisture in the air to prevent drying.

Varieties to choose from

There are stones that exhibit bold fiery colors like the black variety created in volcanic ash. Others are cool and calm like the white ones. Some varieties are created using layers of opal and another clear stone to create texture and more dramatic play of light. Still yet, some gems are removed with their host rock as a background. These are kept in asymmetrical shapes for unique pieces of jewelry.

Special occasions

The (opal birthstone) celebrates the month of October. It is also commemorative of the 14th wedding anniversary. Because of its unique and delicate qualities, this gem also makes a wonderful family heirloom. A wedding present passed from mother to daughter, a sweet sixteen gift or simply as a gift from an estate. If properly cared for, this jewelry can last through the ages and be enjoyed by generations.
