No. As it is synthetic it is man-made. A mineral must be naturally occurring and have a crystalline structure (among other requirements). Synthetic opal does not meet these criteria.
smooth
A synthetic diamond is a mineral made of carbon, and possesses all the same properties as a mined diamond. It has a cubic crystalline structure, a refractive index of 2.42, dispersion of 0.044, mohs hardness of 10 and a density of 3.52.
Mineraloids are a mineral like substance that don't exhibit crystallinity. 5 Examples: mercury pearl obsidian anthracite jet
what is a minerals inorganic solid materials found in nature.
No. Though they may be equivalent, the definition of a mineral includes the description "naturally occurring".
Neither. Opal is a mineraloid, as it does not have a sufficiently organized structure to be considered a mineral.
The types of Opal that i am familiar with are White Opal, Fire Opal, Boulder Opal, Black Opal, Crystal Opal, Light Opal, Doublet Opal, Triplet Opal, Common Opal, Synthetic Opal, and Immitation Opal.
Opal
Opal ia a hydrated silica mineral.
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?
smooth
Opal is a mineral.
Opal and amber are not minerals.
Opal and amber are not minerals.
The fracture of an opal can be hard or smooth , An opal can have as many fractures as any other mineral can . Sometimes opal can be smooth , sometimes they can be hard . The fracture of an opal is hard and smooth .
Opal, (although it's not a true mineral).
Opal is not a mineral, but a silica gel.
