depens on the opal
A real opal will have unique color patterns and play-of-color effects, while a fake opal may have a uniform color and lack depth in its appearance. You can also conduct a scratch test by using a sharp object on a small inconspicuous area; a real opal will not scratch easily. Additionally, a jeweler or gemologist can authenticate the opal using specialized equipment if needed.
It certainly is possible to scratch it, but this stand is scratch resistant and won't scratch easily - but almost nothing out there is really "scratch proof". Generally, no it won't scratch easily.
It depends. Opals range between 5.5 and 6.5 on the Mohs hardness scale (how easy it is to scratch) which is kind of soft, so when used in jewelry they are usually coated with a polymer that provides a thin layer of protection against every day wear and tear. Now, when you say "nail" do you mean finger nail (hardness 2.2-2.5, NO) or a metal nail you hammer? And if a metal nail, made of what metal? See, iron, nickel, and carbon steel are only around a hardness of 4-5 (won't scratch an opal), but some nails are made out of hardened steel which at 7.5-8 WILL scratch an uncoated opal.

Coal does not scratch because it is a soft and brittle material, meaning it can be easily crushed or powdered when force is applied. It does not have a hardness that would allow it to scratch other materials.
