The yellow one is partially see-through.

Both look smoothed: on purpose by a rock tumbler, or by nature abrasion smoothed in a stream bed.

This is an educated guess:

The reddish rose color piece looks like the mineral called rhodonite; a metamorphic origin manganese silicate mineral (Mn SiO3).

The clearish and yellow hue mineral looks like citrine; a form of quartz (SiO2) that has distribution of elemental aluminum in the quartz matrix as an impurity during quartz formation, that gives quartz a yellowish color.

Back in the summer of 1959 or 60, a fellow was mining rhodonite in a high Sierra wilderness area. Using mules, I packed his summers worth of work out to the road. At that time he was getting $2 a pound for the stone. That's my only experience with rhodonite, but I agree, sure looks like what I remember that rock looking like.
