Lapis Lazuli is a block that can be crafted from Lapis Lazuli dye. It is a light blue colour, with darker blue on it. Its only uses are as a building block and as a form of storage of Lapis Lazuli dye. It looks very similar to water, which is why it's sometimes used for easily creating water decorations.
