    A pegmatite is an #igneousRock showing a very coarse #texture, with large interlocking #crystals usually greater in size than 1 cm (0.4 in) and sometimes greater than 1 meter (3 ft). Most pegmatites are composed of #quartz, #feldspar, and #mica, having a similar #silicic composition to #granite. However, rarer #intermediateComposition and #mafic pegmatites are known. Many of the world's largest crystals are found within pegmatites. These include crystals of #microcline, quartz, mica, #spodumene.
