Opal is not classified as a true crystal; instead, it is a mineraloid. Unlike crystals, which have a defined and ordered atomic structure, opal has a more irregular arrangement of silica spheres. This unique structure contributes to its characteristic play-of-color, making opal a popular gemstone despite its non-crystalline nature.
The streak color of peridot is white. This means that when peridot is scratched against a hard, rough surface, it leaves a white streak behind.
No, opal is not quartz. While both are considered silicate minerals, opal is a mineraloid that lacks a crystalline structure, whereas quartz is a crystalline mineral with a defined chemical composition of silicon dioxide (SiO2). Opal is primarily composed of hydrated silica and can form in various colors and patterns, making it distinct from quartz.

Streak is a mineralogical term to describe the colour produced by rubbing a piece of mineral against a (porcelain) neutral background. Since Opal is made from silica spheres, I'd expect a white streak, but meaningless. There may be powdered spheres left behind from the opal structure.
Opal has the chemical formula of SiO2 * n H2O. It has a hardness of 7.0 and has a natural red brick appearance.
