They are however concentrated within the 400km long and 150km wide NE-SW trending pegmatite belt of Central Nigeria. At present only one Lapidary situated in Jos exist in the country where gems are faceted and polished into different shapes. Surprisingly, demand for cut and polished Nigerian gems which have several uses is on the increase internationally.
