Granite - Wikipedia

Granite is a natural source of radiation, like most natural stones. Potassium-40 is a radioactive isotope of weak emission, and a constituent of alkali feldspar, which in turn is a common component of granitic rocks, more abundant in alkali feldspar granite and syenites. Some granites contain around 10 to 20 parts per million (ppm) of uranium.

Quartz and feldspar

The bad news is that sometimes the curved conchoidal surfaces can flash as well, but this usually happens with the clear varieties of quartz (which you already know isn't feldspar anyway). So, if the mineral has cleavage and sparkles, it may be feldspar. If no sparkles, no matter how you rotate it in the light, it may be quartz.
