Looks like it could be opal to me.

I'll say the stones are a difference between first Jasper, second Agate and last Chalcedony. There are grades between these minerals but all are essentially silicate however coloration, patterning and in your case translucence's will vary the grade the mineral receives. Nice stuff though.
