Coober Pedy Calibrated Parcels are cut and polished to fit
in standard calibrated jewelry settings.
Parcels are fire opals, or known as white opals and crystal
parcels are listed under different category
These opal parcels are cut from same rock or same area and
are more uniform than other opal fields in Australia
Most opals are set in 925 silver settings of rings, pendants
or earrings and bracelets and these parcel lots can make matching sets.
Sizes 6x4 or 7x5mm
are most popular opal sizes followed by 8x6 and 9x7 mm
Sizes over 10x8mm are harder to have matching sets
Traditionally only oval sizes were calibrated but today we
cut round, marquis and heart shaped opals
Heart shape opals can also be used for earrings as most can
fit standard round settings with long claws
