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.

#Sunstone is a variety of #feldspar minerals known for its distinctive shimmering or glittering appearance caused by tiny inclusions of minerals. This optical phenomenon gives sunstone its characteristic appearance, reminiscent of the sun's rays. Read more here:

Twinned #feldspar crystals
In a paving stone in #Exeter, United Kingdom, pound coin for scale.
Must have cooled slowly, allowing large crystals to grow, so #intrusive, not #extrusive / #volcanic.

Sort of #selfPortrait in #QuincyGranite

The spectral form, like Jesus looming out of a piece of toast, is me, taking a #photo of a circa 1.5 meter polished granite sphere in the #MountWollastonCemetery in #Quincy. The largest visible #crystals (#feldspar and #amphibole) are about 1 centimeter across.
