I believe that people who buy opal in Taiwan will have such a question: Is the opaque opal fake? And this statement comes from the market. For this unsure statement, how should we easily distinguish the true and false of the opal, is the opaque opal really true or false? First of all, everyone needs to know what is the opal. Opal has been a tribute to the emperor's treasure since ancient times, also known as the cat's eye, mainly made of gold emerald. Its Mohs hardness is 8.5, while Taiwan's opal is a member of the crystal family. Is there a way to identify the opal? For the gemstones in Taiwan, many of them use plausible arguments to mislead consumers. They have different ingredients, but they use transparency to identify whether they are really opal. This is an immoral and uncivilized behavior. Taiwan's opal is hard to be called cat's eye jade. But why is Taiwan's cat's eye jade called everyone's opal? That's because the cat's eye jade contains asbestos inside, which is polished to an egg surface at a certain angle to give it a cat's eye effect, but it cannot be called a cat's eye.
