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.
The most expensive and rare trim of Saffron. Super Negin saffron is known not only for being the most potent but also for its aesthetically pleasing features. Super Negin threads are longer in length and contain no yellow or orange threads. The threads are cut symmetrically and contain no crumbs. When comparing all the trims of Saffron, Super Negin is the most sought after for those who want the best of the best.
When compared to Sargol and Super Negin, Negin is longer in length and contains some yellow and orange portions of the thread. To put it in simple words, the aroma, quality, and purity are still great but you do pay for some portions of the yellow and orange threads, which are lower quality.
