Diamonds Have No Streak AT All..
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.
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.
The streak of Jade is white.
normally white but may streak other colors if the specimen is stained i dont give a duck
Apatite has a white streak.
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)

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.)

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.
Perlite does not have a streak color because it is a volcanic glass that does not leave a streak on a streak plate.
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.
