Can not tell, kinda looks like quartz, if you see something that looks like gold, try a couple of tests.
Does what you think may be gold crush to powder like pyrite or can you smash it flat like gold, soft or brittle like a sulfide fools gold, or is it malleable like gold metal.
scratch a mark, piece of broken china or bottom of the coffee cup, after finishing your drink, is the scratch still gold, or do you get a blackish to red(magnetite) or red-brown streak (hematite) of iron sulfide ore pyritic ores.

If you still suspect gold or you are still not sure what you have here is another test.
Crush and pan it, you can add a few small slivers of lead to your pan (count them).
Your gold (if any) is heavier than your tiniest lead sliver, and pyrite is so much lighter than the lead piece,
In the pan we shake the heavies down and dump the lighter material from the pan, pan till all you have in the pan is gold, black sand, and your sliver of lead, all the pyrite or mica will float out or be washed out of your pan early in the process...
There are several other tests like using chemicals or other methods, but you should not need them at this point if you can see something shining and yellow you wish to know if it is gold or fools gold...
