Spinel pseudomorph after muscovite(?)

An exceptionally interesting specimen with a mysterious past from the classic Burmese site of Mogok. It is a spinel pseudomorph of another unknown mineral, from which the main hexagonal crystal inherited its crystal shape. Some experts believe that the original mineral was muscovite, remnants of which can sometimes be found among the tiny spinel crystals, while others conclude, based on measurements of the crystal angles, that the original mineral was corundum. In addition to its mysterious origin, the specimen captivates with its contrast and delicate coloration.
