Raven's Cauldron Advent Calendar

A 25 day advent calendar from Raven's Cauldron.  A new crystal for each day with a short description of what it is and what it would be used for metaphysically.  A great gift for a crystal lover!  We have 10 calendars per location (10 in Delaware and 10 in Marysville).  There is a special prize in one of the calendars in each location!  Will you be the lucky winner?
