2. What is the character of this stone?
The reason why many people have a fascination for the opal, is its colour. Especially the Black and Boulder Opal from Australia, we can say that each stone has a different and unique colour (There is no same colour stone). Also, even one individual stone you can find various colours depending on the lighting or which way you look at the stone.
Why does each stone have a unique image? We are going to talk about that in Advanced, but let us tell you this unique colour which the opal has. It is called " Play of Colour". What a beautiful sentence! We don't know who said this at the beginning, but this is the right word for the colour of the opals, don't you think?
When you see a good quality of Black Opal, you are the prisoner of the colour.
Have a look of these pictures. These are the photos of same stone but different lighting. The left photo the light is directly above the stone, the right photo, the light is coming from the side of the stone. We have not added extra colour or paint.
This is the "Play of Colour". You now find the photo on the left side has shown different colour from orange to green depending on the light. If you see 100 stones of opals, you can find 100 different colours from them. This is the main reason why opal is so unique compared to other gems.
The pattern of colour has its own name, and it is very important aspect for valuing. We are going to talk about colour patterns in the chapter ADVANCED. So we will go forward to the contents about "types of opal" and " produce area".
