Neither opals or any other gemstone will make you invisible.
no
Opals are actually not minerals, but are classed as mineraloids. This is because they lack a crystalline structure, yet are mineral in nature.
Nobody MADE opals. They're mined out of the ground.

An icubus cannot actually become invisible, but he can make himself appear invisible to one specific person at a time. An icubus has the purpose of seducing women and would usually find it in his best interest to be visible, on account of their natural good looks. However, in the event he does become invisible, it will be while the intended victim is alone.
Opals cannot be used as foods. They are hard, precious stones.
NO
Some opals are known as black opals, this is when they have a mainly black colour. In general a black opal is very dark blue and has flecks of other colours within

No. When opals were first found in Australia, they were not thought to be opals because they were a milky white in appearance. Opals found elsewhere in the world were mostly black.
Opals are amorphous because they lack a crystalline structure. Their formation involves the precipitation of silica spheres in a disordered arrangement, which gives opals their unique play-of-color appearance. This lack of a crystal lattice is what differentiates them from most other gemstones.
