Rough Opal for Sale

The rough opal for sale featured in the gallery above is perfect for the opal cutter or rock collector.

That is to say, the opal cutter may wish to cut them into gemstones or polish them into individual little works of art for the home or office.

On the other hand, the rock collector (amateur or professional) may wish to add them to their collection as something truly unique.

Regardless of what they will be used for these pieces are all interesting in their own unique way.

Queensland Boulder Opal

When it comes to Australian opal, Boulder opal is a type of opal that is only found in Queensland.

The key defining feature of Queensland Boulder Opal is the host rock the opal is found in.

To explain the opal formation event, the most popular theory argues that one hundred million years ago a large shallow inland sea covered one-third of the Australian continent.

The theory holds that the topography around the inland sea was rich in silica.

Over time particles of this silica washed into the sea and bonded with water to form a gel-like substance called hydrated silica or OPAL.

Consequently, the gel flowed into the cracks and crevices of faults and large weathered boulders lying on the ocean floor to create what we now know as Boulder Opal.

Boulder Opal Specialist

At Opal Art Global we specialize in Queensland Boulder Opal.

Basically, we travel out to the opal fields and buy the raw opal from the mines.

We bring the opal back to our workshop on the coast to sort and process.

We don't cut everything.

If we think a specimen is best left natural we leave it that way and put it up on the website for the cutter or collector.
