Fluorite's streak is white because that is the true color of the powdered form of the mineral. The impurities that cause color or tint in a mineral specimen are so insignificant in relation to the true mineral content that they are not visible when powdered.

Calcite halite and fluorite all have perfect cleavages and they can all be the same color. How would you distinguish among them?

You can distinguish these minerals by testing their physical properties such as taste (halite is salty), hardness (calcite scratches easily with a knife, halite is soft, fluorite is harder), and fluorescence (fluorite exhibits fluorescence under UV light). Additionally, you can use a hand lens to examine their crystal shapes or conduct a streak test to observe their powder color.


The color of fluorite changes due to .?

The color of fluorite changes due to the presence of impurities in its crystal structure. Different impurities can interact with light in various ways, influencing the color of the fluorite. This phenomenon is known as "color zoning" and can result in a wide range of colors in fluorite crystals.


Is color a diagnostic or ambiguous property of fluorite?

Color is an ambiguous property of fluorite. Fluorite can come in a wide range of colors due to impurities in its composition, so its color alone is not a reliable diagnostic characteristic. Other properties, such as cleavage and fluorescence, are better for identifying fluorite.
