What mineral scratches quartz but not gypsum and is green in color?
The mineral that scratches quartz but not gypsum and is green in color is called fluorite. It has a hardness of 4 on the Mohs scale, making it capable of scratching quartz (hardness of 7) but not gypsum (hardness of 2). Fluorite is commonly found in various shades of green, but it can also occur in other colors such as purple, yellow, and blue.
