La'al-e-Sohrabaki, a new report on Rostam's family emblem

In his work on gemology known as "Mathnavi-e Javahir-ul-Asrar", Rashid Tabrizi has introduced types of jewels and named a worthless and yellow coloured jewel (garnet) referred to as "La'al-e-Sohrabaki". He has stated the reason of such naming which is related to Sohrab's armlet. He hold that this jewel’s infelicity is the cause of Sohrab's death and the reason of its reputation.This librarian study has two parts. The first part tries to review reliable texts and, in this way investigates characteristics of beads and armlets, particularly those of Rostam's family. The second part is about features of garnet (La'al) and La'al-e-Sohrabaki and tries to state Rashid Tabrizi's opinion about this jewel. According to findings, it is likely that Sohrab's armlet has been adorned with a garnet. However, there is no mention of its colour and price. It seems that tragedy of son killing by the Iranian superhero, Rostam, is never removed from the Iranian minds and this is the reason for this jewel's infelicity in the opinion of Rashid Tabrizi or the people of 10th and 11th century. Thus, the accusation of infelicity attributed to Sohrab's bead of armlet is a popular justification for the exculpation of the hero.
