Peculiarities of the irisation in precious opals in view of their mosaic–cluster (frustumation) inner fabric

Peculiarities of the irisation in precious opals in view of their mosaic–cluster (frustumation) inner fabric

A direct correlation was shown for the first time between mosaic irisation patterns in synthetic and natural precious opals (from Australia, Ethiopia, Honduras, Slovakia, and Russia) and their frustumational (lump or mosaic–cluster) inner structure by means of photoluminescence, X-ray phase analysis...

Zusammenfassung:A direct correlation was shown for the first time between mosaic irisation patterns in synthetic and natural precious opals (from Australia, Ethiopia, Honduras, Slovakia, and Russia) and their frustumational (lump or mosaic–cluster) inner structure by means of photoluminescence, X-ray phase analysis, IR and Raman spectroscopy, and scanning electron microscopy.
