- Opal is a hydrated amorphous form of silica (SiO2·nH2O); its water content may range from 3% to 21% by weight, but is usually between 6% and 10%. Due to its amorphous property, it is classified as a mineraloid, unlike crystalline forms of silica, which are considered minerals. It is deposited at a relatively low temperature and may occur in the fissures of almost any kind of rock, being most commonly found with limonite, sandstone, rhyolite, marl, and basalt.

Many observers considered Zimbabwe’s August 23 elections, which Emmerson Mnangagwa won, as falling short of constitutional requirements, the Electoral Act, and international election standards such as the Southern African Development Community (SADC) Principles and Guidelines Governing Democratic Elections. There were also concerns about the impartiality of the Zimbabwe Electoral Commission prior to and during the elections. The climate of threats, intimidation, repression, and violence against political opponents severely undermined the electoral environment.
