Glitter on my Fingers

Tonight after breaking up some good dank, I noticed some glittery looking pieces on my fingers. Even after rubbing my hands on my pants, the "glitter" remained. This raised my questions on whether this could be the infamous Grit Weed.
I did the tongue test and felt no grit between teeth.
The ash is normal.
No abnormal levels of kif.
Everything looks good except this glitter on my fingers. Starting to worry that I've been smoking this 1/8 for a couple of weeks without realizing. Throat has been sore past couple of days, but it has been cold lately.
Anybody experience this "glitter" on their fingers after breaking up? It's very small glitter, can only see it by tilting fingers under light.
Thanks guys for help.
