Source of Boulder opal:
These gems come from a wide variety of places in the continent of Australia ranging from the southern border of Queensland up to Winton and the little location of Opalton further north. There is a lot of work done bringing a gem like this to a point where it can be used as a ring stone. Giant diamond blades have to break down the huge boulders into manageable size for smaller blades to cut the pieces into smaller items. That is when the diamond grinding process starts and gradually the color is brought from a dull lifeless feature to brilliant gems.
