Can someone PLEASE help me Identify the Gemstones in these Pieces Arizona Estate

[nowthenandagain1]

Can someone possibly help me identify the gems in these three brooches? They are out of an Arizona estate. The lady who made them was from Wyoming if that helps any but she retired to Flagstaff Arizona.  I always appreciate the kindness and help I get through these forums.. Thank you in advance

MY GUESS, from photos alone is you have the first two glass or two other molded or enameled stones, and the last one chalcedony (agate)...moss agate, picture agate, or aventurine.
