The history of Australian Opal is very ancient. It was formed when inland seas covered the central part of the country. About 140 million years ago, the inland sea retreated to form the Great Artesian Basin. Then, heavy weathering began to dissolve silica and water, trapping silicates in the spaces between rocks. As the sea receded, the opals were created. While the process of creating opals is very ancient, finding good quality pieces is rare.
The process of making opal gemstones involves mining it from the ground. It is very difficult to find a perfect opal gemstone because of its inherent imperfections. The genuine ones, on the other hand, are free of blemishes. In fact, they can increase in value by up to 15% a year. In the past, it was impossible for a person to tell which opal was genuine from a fake.
While many people believe that opals are natural, these gemstones are actually fossils. This means that they are made from a plant or animal that was millions of years old. This ancient rock is made of silica, and the minerals found inside are preserved. Other minerals are also present in fossilised Opals. They are the most valuable crystal Opals. They provide fresh information on the history of the continent and the ecosystems that inhabited it.
The Australian Opal is one of the most expensive gemstones in the world. It can be quite pricey, so you'll want to make sure you buy it from a reputable dealer. You can buy artificially grown gemstones, but they'll be cheaper than genuine ones. The only way to find the best piece of Australian Opal is to go to an authentic Opal shop and buy it from them. You can check its authenticity by using a certified online opal store.
If you're buying an Opal online, you'll find that there are several different types of opal available, including white opal. However, a genuine white opal is unique in its appearance and is the only genuine Australian opal. In fact, it's rarer than any other gemstone in the world. Aside from being a natural Opal, it's also very expensive to buy an artificial one.
While there are several types of opal, a genuine white opal is the most prized. A genuine white opal is a hydrated amorphous form of silicon dioxide, and is found in Coober Pedy, South Australia. This gemstone can range in price up to seven percent each year. Its beauty is unmatched by any other gemstone in the world. The value of a white opal can increase exponentially.
Boulder Opal is the rarest of all Opals. It is only found in Australia and makes up less than five percent of all Opal mined. The region of Lightning Ridge is the prime mining area for Black Opal. While most Australian Opals are natural, they can be spotted with a magnifying glass. If you're looking for an artificial opal, you might have to wait for it. There are other options, though.
It's important to remember that assessing the value of an Australian Opal is a difficult task, as each specimen is unique. It is essential to know that the gemstone can vary in color and body hue, and that the exact value of an Australian opal is based on a number of factors. A quality opal will increase in value as it becomes rarer. This is why it is important to purchase a genuine opal.
The modern history of opal mining in Australia began in July 1889, when a young miner named Tullie Cornthwaite Wollaston took 60 pieces of brilliant opal rough to London. She sold the stones to an international jewelry firm and the demand for Australian opals has steadily risen since. Its most famous black opal comes from the Lightning Ridge area in New South Wales and the Mintabie field in South Australia, though it is possible to get black opal from the Coober Pedy fields.
The different qualities and colours of Australian Opal will vary, but the best quality stones will be the darkest in colour. There are three types of Australian Opal: Natural Black Opal, Natural White Opal, and Ethiopian Opal. It is important to remember that white opals are rare and more expensive than other opals. The quality of an opal will depend on its location, so it is vital to research it thoroughly before buying an opal.
