This October birthstone is never out of style. It sets the trend.

Opal stones come in a lot of variety, and every stone is one of a kind. Opals are very easy to identify. Not every gem has a white, pearly appearance and is translucent to opaque. Opals are available in so many colors, and each of them is stunning.

It might shock you, but opal stone was initially not considered a good luck gem or a gem that would bring peace, protection, and harmony. It was considered a stone of evil. An incident from the old days made everyone believe that the stone was connected to evil. 

Opal Gemstone is highly believed to be derived from two Latin and ancient Greek words, ‘oplaus’ and ‘opallius’. The meaning of both words is color-changing. Some might also believe that the Opal stone meanings and names have been derived from the Sanskrit word ‘upala’, meaning jewel.

Back in the day, in a novel by Sir Walter Scott, a lady named Hermione was believed to be possessed. When a drop of holy water was dropped on her, it accidentally fell on her opal necklace and destroyed its color.

Since then, the price has dropped, and people have started refusing to use it. There was no use of rings, earrings, or any kind of opal jewelry.

Years later, when a variety of black opal was found in Australia, people started regaining trust, and the demand went up. Since then, Australia has been the major producer of white and black opals. The rhodochrosite price per gram typically reflects its vibrant pink hues and level of clarity.

While holding an opal stone, you begin to spin it at various angles in the light. Its rainbow of colors will then emerge one by one. And in a range of colors, from white to gray, blue, yellow orange, green, pink, red, brown, and black. Relatively diaphanous (translucent to opaque) and wax leprous.

This is not a rare gemstone. One can find it in locations like Australia, Mexico, and Brazil. It is believed that the stone was first mined in the Carpathian Mountains. To lay your hands on the finest and real opal stone varieties, try going for the ones from Australia. Australian opals, both white and black, are a must-have.
