Here is an example of a much harder to find variety with two stages of Mica. There is an inner mica core with a dark olive filament inside. Then there is clear space between that and the exterior mica shell, like the vast space between clusters of galaxies. Although this double layer doesn't increase the value exponentially given it's rarity, it still holds it's own for the unusual nature and how it makes the mica twice as bright, similar to cased micas. Early Faceted pontil with one small nick. The rest is wet mint Crystal clear and clean. Photos and background make the marble appear off white in colour and that is not the case. Several photos were taken blocking out the light at the top so you could see the inner mica core. Those photos appear darker and focus on the interior of the marble. The bright white photos are those resembling how the mica appears in hand.
