Heart shaped pendant with angel baby on back

My mother was given 2 rings and necklace. The markings on the back of necklace are nothing we have ever seen. We would like to know more about these pieces of jewelry. The ring that is pictured by itself has only a J on the back. All she knows is it was made in arizona. Thank you!

I have a turqoise heart shaped pendant with a small baby angel and a small heart attached to the back. It’s about the size of a half dollar. I did homecare for this elderly woman who thought the pendant came from Arizona. She gave me all her turqoise jewelry and I would like to know somekind of price value. Especially this piece. The turqoise is a bluish color with a light brown mixed in. Please help me, Thank you Joany I’m guessing that she got this in the late 60’s or 70’s?? Thank you
