· Granite ( sensu stricto) is a coarse-grained intrusive rock in which quartz is 20-60% QAP content by volume and alkali feldspar accounts for 35% to 90% of the total feldspar. It doesn’t have feldspathoids. You may subdivide granite into synenogranite with 65-90% of the total feldspars alkali feldspar and mozogranite with 35-65%.

The difference is, that out of more than 200 recognized gemstones, at least 12 of those are variations of quartz, while only 4 of them are variations of feldspar. This is most likely due to the fact that quartz is a harder mineral than feldspar. If something can be scratched or broken more easily, it is considered less valuable.
