I found this yellow stone in a creek.It was easy to break by slamming it against another stone and has evenly spaced crystal clear grains.They are very clear that under the sun I thought that water drops are coming out but then realized they are another type of tiny stones inside the yellow host rock.The grains are 100% clear to the eye and smooth without sharp edges and 0.5 to 1.5 mm in diameter. this stone is so strange that I suspect it's a synthetic material of some kind but where i found it only natural stones can be seen. The stone it self looks like a yellow limestone or something sulfuric. It Was buried in the sand near gravel with its tip sticking out. It was about 30X30 CM flat stone that appear to be broken from a larger one. EDITED:Changed photos

I belive what you have found is reflective road paint,The color is similar to road markings and it do contain glass beads.
It does not look like any natural rock i know of but it do look like this type of material https://en.wikipedia.org/wiki/Thermoplastic_road_marking_paint
I am not saying this is what it is but it is one possibility so please forgive me if i am wrong about this.
