Diamond smile!?

I'm currently working in a distribution centre of a jewelry company.
I sometimes have special opportunity to see such a valuable jewel.
Can you see this?
It's a diamond and 12ct. and its colour grades Excellent.

I was so excited with it and could not stop taking a photo for memories.
I seriously don't know
if it's possible to look like this in the future again!

According to the document,
it's 50,000,000yen(100yen=1AUD) for selling price!
We can buy a wondeful house with this!
