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.

Why is the mineral opal referred to as a mineraloid?
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?
How Many Minerals does A Opal Have?
Opal is composed primarily of silica and water. It is a mineraloid, not a true mineral, because it lacks a crystalline structure.
Does the opal smell?
No, opal gemstones do not have a distinct smell. They are made of mineraloid material and do not emit any odor.
Is tektite a mineraloid?
Yes, tektite is considered a mineraloid. Tektites are natural glass formations that are formed from terrestrial debris ejected during meteorite impacts. They lack a crystalline structure, which is why they are classified as mineraloids rather than true minerals.
How does opal fit in the rock cycle?
Opal is amorphous mineraloid, occurrence : Sedimentary and secondary from the alteration of high silica igneous extrusive rocks
What is the difference between a mineral and a mineraloid?
nothing

What a three examples of mineraloid?
they are obsidian, opal, limonite
What is a mi mineraloid?
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.
What is cinnabar's crystal form?
There really isnt a crystal form. Therefore it is a mineraloid.
Is Fire Opal a rock or a mineral?
Neither. Opal is a mineraloid, as it does not have a sufficiently organized structure to be considered a mineral.

Why the mineral opal is often referred to as a mineraloid?
Opal is often referred to as a mineraloid because it lacks a crystal structure, which is a defining characteristic of minerals. Instead, opal is made up of tiny silica spheres arranged in a more random, non-repeating pattern, giving it its unique play-of-color. This amorphous structure sets it apart from traditional minerals.
What is hardness of opal?
Opal is a hydrated amorphous form of silica; its water content may range from 3 to 21% by weight, but is usually between 6 and 10%. Because of its amorphous character, it is classed as a mineraloid, unlike crystalline forms of silica, which are classed as minerals Opal is a hydrated amorphous form of silica; its water content may range from 3 to 21% by weight, but is usually between 6 and 10%.
