Can Original Fire Opal Be Found in Australia?

Whether you're searching for a unique piece of jewelry or looking to buy a piece of jewellery that's going to last forever, there are several factors that you should take into account when choosing a piece of jewelry. One of those factors is the quality and origin of the gemstone. Here's a quick look at some of the characteristics of Fire Opal From Australia that you may want to take into consideration when buying a piece of jewellery.

Origins

Approximately 97 percent of the world's opals are produced from Australia. This is because the Great Artesian Basin is a region of the country that is rich in silica. It was formed as silica was deposited in the groundwater by the erosion and weathering of rocks over 30 to 40 million years. This made the groundwater slowly harden into a gel. The silica then formed the opal gemstones.

Most Australian opal varieties are found in Coober Pedy, in central South Australia. This is one of the Great Artesian Basin. The deposits are found in non-marine sedimentary rocks. The rocks are often layered..

Mohs hardness

Generally, opal hardness is about 5.5 to 6.5 on the Mohs Hardness Scale. However, some minerals have a different hardness. For instance, jade is slightly harder than diamond, while sapphires are almost twice as hard as diamond.

The Mohs Hardness Scale was first developed by Freidrich Mohs in 1812. The scale uses a relative ease of scratching as a criterion for measuring the hardness of a mineral. The scale uses more than ten different minerals.

In addition to the Mohs Hardness Scale, there are other gemstone hardness scales, such as the Vickers test, Rockwell test, and Brinell test. Each test is based on different criteria. Some are more accurate than others, and some are more costly. For example, the Vickers test requires polished specimens.

Another test is the Rockwell test, which uses a differential depth machine. In this test, you place the specimen between two points and measure how deep the indentation is. The deeper the indentation, the harder the mineral.
