Step 2: Sorting & Cleaning
After being pulled up from deeper levels soil carrying Opal chunks go undergoes several stages then sent through sorting machines where opals get separated based on quality grades according to brightness color patterns weight size cracks etc . Lastly they’re scrubbed gently making sure not damage fragile stones before being exported or brought locally for processing.In order to identify great ‘’fire’’, texture translucency etc., sparkling sawed parts give different looks than unpolished side creating variance inside chambers that form geological specimens relied upon backing policy decisions regarding sustainable future mine activity at site.The rougher/bigger ones often sustain extensive polishing /grinding techniques before selling it re-cement large-scale shards togther harness its vibrant beauty depth get turned into glamorous stone jewellery items loathed worldwide,
These raw or part-cut stones then become available via auctions, online platforms or to local cutters or lapidaries, who take the next step of opal processing.
Step 3: Cutting & Polishing
Typically, experienced skilled workers such as Lapidary (Cutter) cutting and polishing machine appliances defined by individual designs appearance each stone as very one-of-a-kind rock material ensuring cutting away substantial amounts while preserving desirable colors of patterns that define its unique character.

These precious stones are made up of tiny spheres that diffract light to create the mesmerizing rainbow colors that we see in them. Opals are not just beautiful but also hold spiritual meaning for some cultures as they were believed to possess supernatural powers. However, it is important to handle these gems delicately as they can crack or chip easily due to their composition. Overall, opals make for stunning jewelry pieces and can add a touch of magic and wonder to any collection.
Opals have been highly valued for thousands of years, with evidence of them being used in jewelry as far back as ancient Rome. The ancient Greeks believed that opals held the power of prophecy and foresight, while the Romans associated them with hope and purity.
