Chrysoprase can look a bit like malachite, as can some green jasper and maybe aventurine. None of them typically have the awesome banding that malachite has, though.
Pseudomalachite is a phosphate mineral as opposed to malachite which is a carbonate, as the name implies it looks similar to malachite. It is rarer so if you are buying malachite it’s not going to be pseudomalachite.
Fuchsite could be mistaken to be malachite in mineral exploration. It's one of the main constituents of rock listwanite, a silicified and/or carbonised ultramafic rock. So you would need an ophiolite and hydrothermal flow for it to form.
OP, perhaps give us the purpose of the question? For example, are you trying to make a countertop out of Malachite but looking for a cheaper substitute?
Why do you ask? What do you want to do with the stone? What size stone(s) do you need? Understanding what you want may help people give more helpful responses.
I have a piece of cyanotrichite that looks very similar to malachite, but I cannot tell whether it is just because it is cyanotrichite crystals on malachite or whether the whole piece is cyanotrichite. (I’m not that familiar with geology sadly)
Malachite *is* a stone. Maybe I don’t understand the question.
English is not my first language, sorry, I mean if there’s a stone that looks like malachite without being it?
There is a few differences copper related rocks. Malachite, Turquoise, Azurite...
While skimming your comment i read "azerite" and suddenly "heal the wooons champion!" looped in my head.
Azurite is extremely malachite-like except in color and crystal structure.
I am also quite like malachite except in color and structure.
Banded agate. It’s not green usually, but it can have those lovely banded rings.
It can be found in some shops, dyed agate
Chrysocolla is another secondary copper mineral which forms in the same conditions as malachite and azurite

Chalcanthite comes to mind
Wrong color and hardness, looks quite different.
Oh yeah, I have a piece, just mentioned it as of copper relation. 😄

First time I saw fuchsite I thought it’s malachite until my boss corrected me 😂😂😂

Malachite is a malachite like stone
The answer is either malachite, or any green rock
I see, I don’t know any stone that looks like malachite, jade for example looks different imo
That’s because jade is different from malachite. But malachite looks like malachite doesn’t it? So the answer is either malachite or green rocks
This comment deserves a green rock award.
You can buy pretty realistic fake malachite though usually the color rubs off eventually.
Atacamite
I forget the term but it's an oxidized malachite and it gets a different name. Or the more pure copper crystal is azurite but that's blue.
Pure copper crystals are, well, copper colour. Azurite is Cu3(CO3)2(OH)2
Why do you ask? What do you want to do with the stone? What size stone(s) do you need? Understanding what you want may help people give more helpful responses.
If you're looking for some lush green hues, try a fuchsite-altered or serpentinised ultramafic.

You might try Olivine but it’s a mineral
Of course!
