It is amazing as 20 years ago I thought that just Australia produced 99% of the words opals
But today so much is coming out of Ethiopia in Africa and the prices are very reasonable
I have seen the American opal with wood vegetation and now we have Indonesian wood type opals and I find these pleasure to view. They look like petrified wood as black charcoal colour compared to quartz looking opals like honey or Prase opals.
The big question is which country’s opals will rise more in the future?
