Here is a video of gold dust by Yuyuko.

She had already experienced silver dust before, but had not filmed gold dust.

This time we prepared plenty of gold dust. She puts it on her fingers and enjoys the color of gold... but this time, it seems to dunk from her face. In an instant, she transforms into a face of gold. Again and again, she repeatedly dunks into the gold liquid. After everything has turned gold, she covers her head with the gold liquid.
