Onyx or Agate is another ornamental and precious stone that is very small in shape and its color is light. Onyx stone with red, white, and yellow colors is widely used and is one of the most valuable and precious stones. Another name is agate which is polished like glass and is semi-transparent. The main composition of this type of rock is silica. 

The original locality for lapis lazuli is the Sar-e-Sang deposit in Afghanistan's remote Badakhshan district. In the Achaemenid period, azure was called "Kabutkeh". In the Sassanid period, azure was consumed a lot. The roof of Ctesiphon, as well as various sculptures, is made of azure; it is possible that they used azurite instead of azure in making these works. 

Agate is found in abundance in Iran and so far more than fifteen cases of agate minerals that six cases are economically exploited. Agate deposits in Iran have been found in modern Oligocene volcanic rocks up to the present day, all of which have precipitated silicon-rich acidic solutions within the cavities.

In 2010, US Pentagon officials, along with US geologists, uncovered approximately $ 1 trillion in untapped mineral reserves in Afghanistan. A Pentagon note says Afghanistan could become Saudi Arabia's lithium. Some believe that intact minerals are worth up to $ 3 trillion.
