Beautiful gem grade Australian Coober Pedy rough opal. Please note this big chunk of opal rough has some crazing as seen in photos and videos. 

I can only see crazing on one side of it where the black spots are and only one line on other side of the stone. I am not sure how deep is this crazing. This is beautiful gem opal has 10mm thickness and I am sure someone will be able to cut many small and bigger stones out of it. 

Larger piece dimensions : 56x34x11
Small piece dimensions: 46x26x10

Photos were taken by mobile phone, wet and under artificial light to show real color.
