This boulder opal mineral specimen is from Quilpie, South West of Queensland.

At Opal Art Global, we have been cutting and polishing opal for over thirty five years specializing in Queensland boulder opal.

We travel out to the mines to buy the raw opal and bring it back to our workshop on the coast to sort, process and cut into the various products showcased in the store.

When we cut and polish a boulder opal mineral specimen we endeavor to shape the rock around the opal to create an artistic rock sculpture.

Each polished boulder opal mineral specimen is an original.

The boulder opal specimen above has been cut and polished the traditional way by using diamond saws and grinders to break the piece down (and shape).
Once shaped we then use wet and dry sandpaper, of varying grits, to achieve a pre-polish.
The final stage is to polish on a leather wheel using tin oxide powder.
The objective of polishing is to remove all the scratches and give the piece a smooth finish.

This specimen is large enough, and sits flat enough, to make a great paperweight, talking point or feature piece in the showroom window of a store.

Because the specimen is polished all over and has a good weight it is nice to handle (tactile). For this reason, polished boulder opal specimens not only look good but feel good too!
