Modern technologies of natural stone processing allow widely use beauty and elegance of marble in interior decoration. Marble in St. Petersburg can also be found in interior decoration of the Royal palaces.

Marble belongs to metamorphic rocks formed as a result by recrystallization of carbonates (carbonaceous compounds) more than 2.5-4 billion years ago under influence of high temperatures and pressure. In process of recrystallization in metamorphic marbles, as a rule, all traces of original clastic grains or fossilized organic destroyed residues. The composition of marble doesn't change with metamorphism. Initial carbonate rocks for formation marble, as a rule, in most cases are limestone or dolomite. Accordingly, marble consists of calcite (calcium carbonate), or dolomite (calcium and magnesium carbonate), or both minerals.

Marble can be white or colored: pink, yellow, gray, blue, greenish, reddish, black, brown, as well as various combinations of these colors are inherent in marble. Often, workers find different shade of color in one deposit. Various shades of marble arise due to content of more or less oxides various metals and graphite. Colored marble is characterized by presence of veins, which cracks filled with natural cements. These veins can form an original pattern. The most valuable type of marble is pure, white statuary marble, for making sculptures.
Marble rock-solid, wear-resistant, blackout, decorative, easily processed and easily polished.
The volume mass of marble varies from 2.3 to 2.6 t / m3, porosity of marble from 0.6 to 3.3%, compressive strength of marble from 30 to 153 MPa, hardness of this natural stone on the Mohs scale from 3 to 4, water absorption of marble is in range from 0.02% (Levadia) to 3.3% (Travertino).

Marble almost always contains impurities of other minerals (quartz, chalcedony, hematite, pyrite, limonite, chlorite , etc.), as well as organic compounds. Admixtures differently affect quality of marble, reducing or increasing the decorative effect of this natural stone. But sometimes nature presents real surprise. For example, sections of some types of Italian marble (Nero Fossil), you can clearly see fingerprints of ancient molluscs. Such stones can be beloved forever. Most colored marbles have motley color. The pattern is determined not only by structure of marble, but also by direction in which the natural stone is cut. The color and pattern of the marble appear after polishing.

Over time, the word marble has expanded to include semi-dense and dense polished limestones used as marbles. From the point of view, market, the expressive content of the word further expanded to understanding under the marble of all stone-like materials, amenable to sawing on plates and mirror polishing.
