Opal is an amorphous form of silica related to quartz, a mineraloid form, not a mineral. A mineraloid is a mineral-like substance that does not demonstrate crystallinity.Now you get it?
A billitonite is a variety of tektite - a mineral from Southeast Asia.
A mineraloid is a naturally occurring substance that lacks a crystalline structure, which distinguishes it from minerals that have a well-defined atomic structure. They may have a chemical composition similar to minerals but do not exhibit the same regularity in their internal arrangement of atoms. Amber and opal are examples of mineraloids.
Opal is composed primarily of silica and water. It is a mineraloid, not a true mineral, because it lacks a crystalline structure.
No, opal gemstones do not have a distinct smell. They are made of mineraloid material and do not emit any odor.

they are obsidian, opal, limonite

A mineraloid is a naturally occurring substance that does not have a crystalline structure like minerals. Instead, mineraloids have an amorphous or non-crystalline structure. Examples of mineraloids include opal and obsidian.

There really isnt a crystal form. Therefore it is a mineraloid.
Neither. Opal is a mineraloid, as it does not have a sufficiently organized structure to be considered a mineral.
Australite is a form of tektite, a small, round, dark object formed by the rapid cooling of meteorite fragments which hit the Earth.

A tektite is a drop-shaped glassy object formed from impacting meteorites on Earth's surface. Moldavite is a specific type of tektite with a button shape, formed from a meteorite impact in the Czech Republic about 15 million years ago. Both tektites and moldavites are prized by collectors for their unique origin and rare beauty.
