How to make realistic gold ore?

[Z3KY0 (Zekyo)]

I’m not an expert, but I think you could do something like this but with some glitter as a visual trick for the player:

Somewhat a glitter effect with 2D planes

So that it looks kinda like this when you turn your camera

Maybe this was not the kind of appearance you were looking for, scratch this.

+Also, have you already thought about creating a seamless animated texture to simulate the “sparkly effect” you want on different spots of the ore?
