The definition of the opal is " Non crystallised minerals made by silicon dioxide combined with water".
Do not panic. This is not what we are going to tell you. But this is the definition. And it means.....,
Do you know the things in a small bag which you can find in a package of rice crackers or sometimes in a package of a computer. Maybe you don't know. Ok, how about this. For protecting clothes from humidity, some people put a product called silica gel into their closet. Yes this is it! We believe you have some kind of idea about these tiny blue particles, this is the opal. But don't think like " opal is just a cheapie thing". We say that, because it will give you a little idea about the opal. In a manner of speaking, we can say the diamond is the same as "the coal" or "pencil".
The opal is made from the same minerals, but the comparison to the opal, takes more than 60 million years to form and silica gel which takes few hours to make in factory by a human. We believe you can understand the value difference between each other. Also a silica gel doesn't have beautiful or brilliant colours. What do you think? Do you think you have different cognition of the opal now? So we are going to learn the reason why the opal is so unique, and what type of character the opal has.
