Although Persian Sargol is considered as the premium saffron, there is another variation of Sargol Saffron. If three stigma threads are attached together and form a cluster, this type of saffron is called Negin.

Since production of Negin saffron is an extremely delicate and precise manual skill, it is the most expensive type of saffron and very limited to offer. The ISO reading of Negin is usually more than 270.
