Seller: paropamiso.gioielli (667) 100%, Location: Venezia, Ships to: Americas, Europe, Asia, Item: 121580480273 Condition: Good condition., Material: Rock Crystal, Details: Nice Chinese rock crystal faceted bead. The transparency allows to see the way used to drill the hole and it proves that it is made of natural and untreated clear rock crystal (not glass, led crystal, 'fused quartz', pressed quartz, 'Asian Quartz' or 'Chinese Quartz' which are in fact all made from glass). It probably dates to the Warring States Period (475 - 221BCE). The surface presents wearing signs commensurate to the age, and the fraying arond the circumference indicates a very very long wearing..
