Limestone and Marble blocks

This proposal suggests adding two new natural stone types to Minecraft: Limestone and Marble, along with a full set of decorative variants craftable through the Stonecutter. These blocks would expand building diversity, support new biome generation concepts, and enhance creative and survival building options. They should be able to be crafted into slabs, stairs, walls, and all the variations that other stone blocks can be crafted into. I think these blocks would add a beautiful color scheme for builders and give caves and landscapes a more diverse look, adding highlights to the already beautiful worlds.
