A geode containing a number of of brown calcite rhombs, from a new find near Mumbai.  I saw a few of these in Tucson this year (priced more expensively), so the find is probably around 1 year old.

The Indian dealers have been calling these "mica."  On  this specimen, the calcite rhombs are rather thick, but on others, the calcite exists as very thin sheets of rhombs, hence the "mica" description.
