A #macrophotography #photo of a bunch of small #carnelian #crystals in an #antique #glass #jam #jar. Carnelian is a form of #chalcedony colored by #IronOxide #inclusions, usually hydrous, and ranging from submicroscopic to microscopic in size.
Chalcedony itself is another form of #SiliconDioxide, #SiO2, in a #cryptocrystalline form. Its crystal structure is made of many small crystals whose structure is only visible under a microscope.
Despite have the same #ChemicalFormula, #Quartz and chalcedony look wildly different from each other.
What kinds of “#gems” await in places where #WaterIce is harder than rock?’
The jam jar is also SiO2 in a different state. How versatile is CO2? Can you keep jam in it?

The truth is...

When doing building inspections, fire marshals often overlook the use of flint as a building material.
