When picking a ring, you can also pick a finish. Different metals support different finishes from polished, matte, satin, etc.
High polish is the most common type of finish. A high polish finish is a smooth, shiny, glimmering finish. You can always get a ring polished at a jeweler's every few years if it loses its finish through wear and tear or polish it yourself with a jewelry wipe.
A matte finish is a popular, modern style. Matte finish has little to no shine, providing less reflection and less shine.
If you can't decide between the two, you can always get a combination finish, which is somewhere between the matte and high polish finish!
A hammered finish is a textured finish. The ring will not look like a smooth piece of metal, instead, it will look handcrafted, with each detail pounded in with a hammer.
