So gold ore is not necessarily gold colored, but rather it can looks like any other rock that you might encounter. The exception to this would be truly high-grade gold ore that has actual gold veins running through it. This type of gold is exceedingly rare. People almost NEVER find it picking up the random rock off of the ground.

In various gold ores, the native gold commonly occurs as tiny particles contained within sulfide minerals such as pyrite. Iron pyrite is an exceedingly common associate with gold, but it also serves as a reducing agent. Therefore whenever gold is found encased in pyrite, it is always present as free gold and not as some type of gold sulphide.
