Inked Carnelian. Ottoman Empire. c. 1800-1850 CE. Round intaglio with inked positive script. Text: Allah, Muhammad, Ali, Fatima, Hassan, Hussein "The Shi'ite Prophet's lineage"It's important to note that the Shi'ite lineage of Ali is strictly adhered to by only about 25% of Turkish Muslims. More than probably, these gems, though Ottoman, were probably made outside of Turkey itself and more than likely are of eastern manufacture..
