- Title
Large Baroque "Golden" South Sea CULTURED PEARLS.
- Authors
Hyatt, Akira
- Abstract
The article discusses the gemological properties of a pair of large undrilled baroque South Sea cultured pearls examined by the East Coast laboratory. The cultured pearls were found to have a slight difference between their bodycolor which were variegated. The Gemological Institute of America (GIA) Pearl Description System noted that both cultured pearls had very good luster and appeared only lightly blemished for baroque pearls. X-radiography revealed the presence of bead nuclei with varying nacre thicknesses. Visible-range spectroscopy was suggestive of the specimens natural color origin.
