Articles opal cutting the most important procedure by far is orientating the rough because if this stage is incorrect then you will lose large amount of color and there is nothing you can do to fix the problem, all the polishing and cutting will not put the color back. This procedure takes many years to learn and the only way to learn is to rub down as much low grade inexpensive rough as you can possibly fine .   Please remember black opal is different to crystal and boulder stones is different again ,learn your particular type of opal and remember just because you understand one type of Australian stone,  if you go out to the Queensland boulder opal towns to buy boulder, you have specialized in orientating and cutting crystal for example then you really need to change your approach and thinking slightly.
