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 a 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.
