To trace a diamond and a black opal

Have you ever watched the movie named "Blood Diamond", starring by Leonardo Dicaprio?
You might know about the horrific atrocities in Sierra Leone and the long suffering of the people of Angola, and the movie is about "Conflict Diamond" , which have helped to sustain those African conflicts since the end of the Cold War.

Today, The international diamond industry has already taken steps to increase the diamond industry's ability to block conflict diamonds from reaching market. Although, their origin is difficult to trace and once polished, they can no longer be identified. This is a fact which we all have to think to encourage real peace.

Talking about Opal, it is not very difficult to tell "where they come from" on Black Opal. Because the field where we can find them is extremely limited, and also the annual ammount of black opal minded in that area is only a small.

So don't worry! There is no "Blood" when we mine Black Opal!!
(However, there is another problem for miners and opal dealers...)

Have a lovely evening...xxx
