The Mary's Bean (aka Crucifixion Bean or Crucifix Bean) grows in just a few areas of tropical America, particularly forests of Guatemala.This bean holds the record for the longest recorded drift: 15,000 miles.Size is 20 - 30 mm. in diameter, 15 - 20 mm. thick, with a hard lustrous surface, black to brown or intergrades between the two colors.One side has two grooves (the hilum) forming a cross.It is this mark that gives the bean the name "Crucifix Bean" and why the bean has a deep religious significance for some who find it.
