The gold content of this piece has been tested using standard accepted testing methods, such as acid testing. The brooch and fixture are 10kt. yellow gold. The bezel is in 14kt. yellow gold. The opal size was calculated using a standard jeweler's caliper. The opals were tested using a jeweler's stone tester. The stones were not removed from the piece to do physical testing or for weight. The opals are assumed to be Australian opals and could possibly be backed.
