Rock identification from Jamaica
« on: 25/08/2014 18:50:53 »
My parents brought home some rocks for my daughter from Jamaica.  If anyone could let me know what they are, I'd appreciate it.  I think the top two are different from the bottom two.  The white lines on the upper two turn blue when wet as evidenced by the upper right rock.  The bottom two do not change color. 
Thanks
