well i really don't know sorry. Here are some useful things close to that...
1. Mica shows clear cleavage.
2. Hardness is a measure of how easily a mineral can be scratched.
ill tell you as soon as possible when i figure it out! Thank you
i have no idea..... but its probably a no .. take my advice.
Graphite
Diamond will not leave a streak on a porcelain streak plate because diamond is harder than the streak plate. It will leave a scratch on the streak plate for the same reason.
The mineral corundum, with a Mohs hardness of 9, will be harder than a ceramic streak plate and therefore leave no streak.
A streak plate has hardness of 7 on the Mohs scale, so harder minerals will not leave a streak. Diamond has a hardness of 10 and corundum is 9 - so neither will leave a streak.
Graphite is a mineral that does not leave a clear streak.

Graphite
The mineral graphite is soft enough to leave a mark on paper. We use graphite, which is a form of carbon, as pencil lead. And it works pretty darn well at leaving marks on paper.
Shale is a type of rock, not a mineral. Streak is used to help classify minerals. It can leave a streak, but it doesn't mean anything.

The lack of a streak would indicate that the mineral is harder than the streak plate, or the color of the streak is the same as the color of the streak plate.
Diamond will not leave a streak on a porcelain streak plate because diamond is harder than the streak plate. It will leave a scratch on the streak plate for the same reason.
Graphite leave clear traces on paper, wood etc.
Nickel leaves a silver-gray streak. Note that nickel is an element.
Minerals with a hardness greater than around 7 on the Mohs hardness scale will not leave a streak on a standard unglazed porcelain streak plate. They will instead scratch and powder the streak plate.
It leaves a scratch instead of a streak because Topaz has a higher number on the Moh's scale compared to the streak plate.
