Tiny real geodes, Mexico. 1:12 or 1:24. Sold individually

Tiny real geodes!  Sometimes called baby geodes, these come from Mexico.  For some reason I struggled to photograph them well to show the details.  All have lovely glittery interiors and the left and right ones have definite red speckles around the cavities.  They all have dark green "rinds".  All are mounted so that they are ready to display as shown.  These specimens can work in 1:12 or 1:24 scales.  I've shown them on a 1:24 table.
