This review is spoiler-free, I won't give you any information you wouldn't find out by searching it or by reading the first chapters.
An absolute joy to read, both on it's visuals and the writing.
"Land of the Lustrous" is captivating, it looks like nothing i have ever seen and has an amazing use of the constant black background to craft loads of striking scenes coupled with dialogue that perfectly fits what it's trying to convey, this wouldn't be nearly as much of a masterpiece if didn't had this specific artwork. While it may not be as detailed as most manga are, this kind of composition works
together with the narrative to create an absolutely outstanding piece of art.
Our protagonist is androgynous looking like almost every character in the story, his goofy and lazy personality allows for a much easier start and for us to easily relate to the character of Phosphophyllite, it tries to drag you in as soon as it can and doesn't waste your time, early establishing the main, elegant-looking enemy and the element that makes the entire story flow as it does, the physicality with which the Gems are broken. Not only does it look great, but it adds to the overall whimsical feeling and plot, by chapter one you already know what can happen to these characters and the chance that they can be rebuilt, it makes you ask questions about the moon and it's dwellers constantly, but you'll have a long way ahead to get those answers.
Reading the first chapter again surprised me by how many things it established I just didn't knew where that important and the great foreshadowing, it's very clear that Ichikawa Haruko had a very good grasp of what she wanted this series to be and created a structure in which she could execute all that.
It already starts off pretty interesting and good looking, and from then on, it goes to develop and entertain you with different things that have a believable relation, I never doubted the reasons of a character to be where he is or do what he does, and I definitely never doubted the flaws the characters have, they're not perfect, you may think that they would be after knowing how they look, but the first three chapters talks about three different characters and how they are far from perfect.
While the moon is one of the main elements of the story and being taken to it is clearly a sign of the characters losing, I felt that maybe it wouldn't have too much tension and payoff to the great buildup, I was terribly wrong, i'm not talking about the answers the series gives later on, even tho they are great, i'm talking about how satisfying it is to watch our character's tales.
Every time they broke beautifully, they get rebuilt and as result become easier to be broke again. Some series where characters can't be killed use things like cutting of a limb to take something away from the characters, so having immortal characters that can be rebuilt and not knowing exactly what happens on the moon may sound like the tension would be drain out by the circumstances, but it doesn't, the series actually manages to have a incredibly good body horror aspect both visually and narratively, which creates some of the best looking fight and presentation scenes I have seen in my life.
I could go on about the specifics, but that would be spoiler territory, and I don't want to ruin anyone's possible amazing experience with this masterpiece, I strongly recommend this and it's anime adaptation to literally everyone, as even the CG looks great.
Fascinating concepts, great character development and portrayal, this manga manages to masterfully balance fantasy, horror, action and comedy in a package that I can easily say will be my favorite manga for a very good time, maybe for the rest of my life, since one of the reasons I don't read too much are because most of then don't interest me and I just find anime to be easier to consume.
I can't praise this as much as I wished to, so i'll stop here and go watch something as you go read it, and I hope you find it as amazing as I do.
