LUCA- ETHIOPIAN OPAL DOUBLE LAYER LONG NECKLACE
Double layer gold filled and Ethiopian opal necklace. About 30 inch long chain on its longest layer.
Many of the opals mined in Ethiopia, especially from the Welo deposits, are hydrophane opals. "Hydrophane" is a name used for a porous opal that has the ability to absorb water. A change in color or transparency often accompanies the water absorption.
