Iran is one of the largest pistachio producers in the world and has been able to become one of the centers of export hubs due to the high quality and wide variety of pistachios produced in this country. There is great diversity among pistachio cultivars but four of them are known more than the others and are available in the market (It is noteworthy that the RedRuby International Co offers pistachio cultivars of the highest quality to its customers):
The pistachios are rectangular (almond) in shape, a high percentage of the shells split naturally before harvest, nut surface color is purple and the the shell is very light-colored.

There are 20-22, 22-24, 24-26, 26-28 or 28-30 pistachios per ounce.
