As discussed previously, stone was formed from different types of natural minerals. Marble’s main consistency is calcium. Calcium carbonate is the natural source that bonds the stone. Certain additive minerals blended into during formation to customize these brilliant colors. The additive minerals are also color developers present in granite and other natural stones.

Stone Color	Mineral
Black	Biotite, Hornblende, Carbon
Brown	Limonite
Gray	Variety of minerals
Green	Mica, Chloride, Silicate
Red	Hematite
White	Feldspar, Calcite, Dolomite
Yellow	Limonite

Mineral	Mineral Color
Augite	Brown, Green, Black, Purple
Biotite	Black, Brown, Green
Calcite	Pearlenscent and Pale Colors
Dolomite	Colorless, Pink, Pale Brown
Feldspar	Yellow, White, Pink, Green, Grey
Hematite	Metallic Grey or Black
Hornblende	Green, Yellow, Brown, Black
Limonite	Black, Brown, or Yellow
Sulphur	Pale Gold

Minerals have a variety of crystalline properties. For instance, Augite (listed above) has different crystalline properties. Each property has its own color. Stones brilliant colors and various crystal formations developed when different mineral properties blended together along with the integration of temperature and pressure.

The veins and color grains of marble were liquid minerals that flowed through the stone when the Earth heated up. The intense heat softened the limestone to allow the liquid to flow through it. When the Earth cooled, the mineral flow stopped and gradually hardened to its state.

The delicate colors of stone often can altered by the improper use of cleaning chemical, mopping with dirty be solution, using chemicals that are not designed for stone care, and sunlight can fade the color of natural minerals.
