Question

I play Pokémon emerald a lot and I have never encountered a shiny pokémon before so where and how do you get one???
The same for brilliant diamond.

Wait emerald is a totally different game than brilliant diamond you should ask two different questions

The odds are 1/8192 in emerald and 1/4096 at base in BDSP. You have to get lucky unless you plan on hunting them

There are several ways to raise your shiny chance in BDSP, like Masuda method, Poke radar, Grand Underground, and outbreaks. In Emerald, the only way to get it higher than 1/8192 is by abusing the RNG, which you can read about here: https://www.smogon.com/ingame/rng/emerald_rng_intro
