Original deposit/sedimentary rocks are compacted by particularly high pressure of the earth layers deposited. Pressure and heat change the structure and color. Limestones are formed mainly in seas and in lakes and consist mainly of calcite. Yellow and brown colors are caused by limonite, red colors by hematite and gray and black colors by graphite. When the masses are caked, some of the structures present in the original material are lost and new, breathtaking colors and structures are created.

Natural stones are not formed in one day. The formation takes many millions of years. Often, various transformation processes follow each other until the natural stone reaches the surface in its current image.
