Real opals are natural gemstones formed from silica and water, often containing small amounts of other minerals. They are known for their unique play of color, which is caused by the diffraction of light as it passes through the tiny silica spheres within the stone. Real opals can come in a variety of colors and are often found in Australia, which is the world's leading producer of opals. These gemstones are highly valued for their beauty and rarity, making them a popular choice for jewelry. **

Opal mining in Australia typically involves searching for opal deposits in areas known for opalization, such as Lightning Ridge, Coober Pedy, and Andamooka. Miners use various methods such as open-cut mining, underground mining, and tunneling to extract opals from the earth. Once opal deposits are found, miners use tools like picks, shovels, and machinery to extract the opals from the surrounding rock. It is important for miners to have the necessary permits and follow regulations set by the local authorities when mining opals in Australia. **

One can make money with opals from Australia by purchasing raw opals from miners or wholesalers, cutting and polishing them to enhance their beauty, and then selling them as finished gemstones to jewelry designers or collectors. Another way is to create custom opal jewelry pieces and sell them through online platforms or at jewelry shows. Additionally, investing in high-quality opal mining operations or opal mining leases in Australia can also be a lucrative way to make money with opals. **

I'm sorry, I cannot physically see the opals you are referring to. However, if you have opals in your possession and are unsure of their authenticity, it is best to have them evaluated by a professional gemologist. They can assess the opals and determine whether they are real or not based on their characteristics and properties. **

Yes, there are other stones that can change the color of opals. For example, if the opals on your necklace were initially white and have now changed color, it is possible that they were paired with a different type of stone that caused the color change. Some common stones that can influence the color of opals include black onyx, turquoise, and lapis lazuli. It's important to consider the possibility of these stones being present in your necklace if you notice a change in the opal's color. **
