Calibrated Opal Doublet Parcels

High Volume Production Efficiencies

For commercial designers and wholesale manufacturers, calibrated doublet parcels are the most efficient way to build high impact and budget friendly jewelry lines. Unlike freeform stones that require custom jewelry castings for each individual piece, our calibrated parcels are cut to exact standardized measurements. This dimensional precision allows designers to use standard commercial settings, drastically reducing expensive labor costs.

Natural Backings and Premium Quality

We use natural Queensland ironstone or black potch backings instead of industrial plastic. This ensures our doublets display an organic and high quality look that synthetic options absolutely cannot replicate. Research from the Australian Museum highlights that natural ironstone provides a dense and incredibly stable host material for assembled gems. You can view our finished jewelry to see how beautifully these composite stones perform when mounted securely in professional settings.

Solid Margins for Commercial Jewelers

Purchasing these stones in bulk parcels provides exceptional margins, allowing jewelers to create brilliant black opal look collections at a fraction of the cost. Because the top slices are ethically mined from South Australian fields, you get genuine Australian opal color play.
