Diamond Hash is one of the most potent strains of hash in the Afghani family and is produced everywhere in and around the country. Despite its Middle Eastern heritage, use of this strain has quickly spread throughout Europe and North America, and Diamond Hash is now considered to be one of the classics.

As with other Afghani strains, Diamond Hash is made using resin derived from the buds of mature cannabis plants (traditionally indicas) that have been ground into a fine powder and pressed into thick blocks by hands using small amounts of tea or water. This unique process is characteristic of Afghani hash manufacturers and is what gives Diamond Hash its rich dark color as well as its firm consistency and earthy aroma.
