Native gold is the only ore of gold, a precious metal. Native gold is very common in igneous layers, a bit less in sedimentary layers.

When mined, hunks of native gold are called gold nuggets. Gold nuggets can be smelted to produce 4 gold bars. Gold nuggets can also be smelted with a silver-bearing ore to create the alloy electrum. Using low-value silver ores (galena and tetrahedrite) in this reaction will result in a net value increase for your fortress (electrum bars are each less valuable than gold bars, but you will have twice as many total bars).

Native gold is just as valuable as metallic gold, so if you have a decently skilled stonecrafter and did not start your metal industry yet, native gold mugs are very good to quickly boost the value of your starting fortress and/or buy stuff from an early caravan. However, melting the gold will make far more bars and generally more wealth.

In real life

Native gold is not technically an "ore"; it's merely chunks of mostly-pure metallic gold, naturally formed. As gold is an extremely unreactive metal, this is by far the most common form in which gold is found in nature.
