The two unusual properties of calcite are:
1. Calcite fluoresces (floor-esses), that is, it glows, when ultraviolet light is shone upon it.
2. Calcite is birefringent (bye-ree-fringe-unt), which means that it bends light that hits it not once, but twice. So if you were to look through a flat, clear sheet of calcite, you would see everything double.
the shape and color and quartz is glassy and calcite isn't.
Special properties are unusual properties a mineral may have that most minerals don't.
It is not magnetic. hello everybody
Calcite is a compound
No. Calcite is another name for calcium carbonate. CaCO3

cloaking device, they use calcite's birefringence to bend light around objects seen with the human eye.

After my opinion nitrogen hasn't any unusual and very specific properties.
The minerals aragonite and calcite has the same formula - CaCO3 (calcium carbonate). But all the physical properties are different.
Calcite bends light in a certain way: Double refraction (Double image)
you use the scratch test
