Thanks, I did find some garnets with these which I will also post in the rocks and gem section...
You may want to post under "rocks /gems"
However in my opinion from the photos The first one appears to me to be yellowish but your description says green Hmmmm yellow/green makes me think "olivine?" which is Peridot also known as Chrysolite which is a beryl, however your specimen is not gem quality.
Now as to your second specimen I believe you have an example of Pyrope also known as garnet or corundum, (cape ruby) once again specimen grade only not gem quality. The color is what determines the name of the same mineral that is why there are so many names that apply to the same mineral making it even more confusing for the novice.
Nick's pictures are chromian diopsides (garnet) (peridot) also called cape emeralds they appear to be of gem quality. (notice how clear and without inclusions or fractures they are)
Hope this helps ,
