White jasper or fossil?

I'm having a hard time identifying this stone. It's hard opaque and some translucency has small dark spots in it found in New Mexico.

I'd call it smoothed Quartz, which gives it a Jasper look and feel.
It might be from a pegmatite originally where it picked up the little black spots?

Yes, looks mostly to be silica.  Obviously nothing in nature will 100% pure so this quartz has inclusions of potentially manganese oxides, mica, or hornblende, for the black spots and probably other common minerals like feldspar are mixed into your specimen.
