muscovite  with inclusions
Muscovite is KAl₃Si₃O₁₀(OH)₂
Normally, a thin sheet of high grade muscovite mica is almost perfectly clear and

transparent.  However, sometimes impurities of rutile and various oxides of iron are

present and create patterns rivaling modern art.  Often the impurities align with

crystallographic directions within the muscovite, creating hexagonal network

patterns.
