The streak for a diamond is colorless.
limestone has a white streak.
It leaves a scratch instead of a streak because Topaz has a higher number on the Moh's scale compared to the streak plate.
Flint would have a white streak.
I do not have a picture, but when you scratch aquamarine on a streak plate, the powder will be white colored.

Diamonds are the hardest substance on Moe's Hardness Scale and as such don't have a determined streak color (since streak is determined usually by a clay tablet of hardness ~3)
The streak of a diamond is transparent.First of all, diamond is spelled 'diamond'. Next, diamond might seem like it has a streak when it scratches something but that is only a scratch. Diamonds do not have a streak.
A diamond's streak is the color left behind when a diamond is rubbed against a rough surface. This streak is typically colorless due to the hardness of the diamond, which prevents any significant amount of material from being left behind.
a sapphire doesn't have a streak.
Diamond does not streak. Anything with a Mohs hardness greater than about 7 will cut the ceramic plate used for the test. Diamond, the hardest naturally occurring substance, has a Mohs hardness of 10. (Nothing else in nature comes close.)
Very hard minerals like diamonds can leave no streak because their hardness prevents them from being scratched by the streak plate. Since the streak test involves rubbing the mineral against a surface to leave a streak, extremely hard minerals won't leave a streak behind because they are tougher than the testing material.
Minerals that cannot be determined by a streak plate typically include those that are harder than the streak plate itself, such as diamonds and corundum, as they will not leave a streak. Additionally, minerals that are non-metallic and have a very light color or are transparent may not produce a visible streak. Furthermore, minerals that are powdery or have a very fine texture might not yield reliable streak results.
No, because they are rocks. Mineral rocks to be exact. Want more info? Keep reading... Diamonds are the hardest rock ever known Streak is colorless Level 10 on the Mohs scale Luster is Adamantine
The tests you can do is the streak test, the luster test,the finger nail test(which is scratching it ti see if its hard or not).
The term "steak of diamond" is likely a typographical error or miscommunication, as it doesn't correspond to any recognized concept in geology or gemology. If you meant "streak of diamond," it refers to the color of the powder left when a mineral is scraped across a streak plate. Diamonds, however, typically leave a white streak due to their hardness and lack of color in powdered form. Please clarify if you meant something else!
The streak of Jade is white.
Gem-quality diamonds are available in most every colour, most every shade of colour, including shades of colourless diamonds. You can read more about diamonds, including possible colours, below.
