Marble is a beautiful stone formed deep underground when limestone is transformed by intense heat and pressure over millions of years. Pure marble is white, but minerals mixing in during formation create stunning patterns: swirling grays, warm creams, deep greens, even pink or black veins running through the stone. Ancient Greek sculptors loved marble because they could carve it into incredibly detailed statues that seemed almost alive. The Parthenon in Athens, built over 2,400 years ago, still showcases marble's durability and beauty.

Architects and builders prize marble for important buildings and monuments because it's both strong and elegant. The Lincoln Memorial in Washington, D.C., the Taj Mahal in India, and countless museums and government buildings feature marble columns, floors, and walls. When polished, marble develops a smooth, glossy surface that reflects light beautifully.

The word also refers to small glass balls used in children's games. When someone says they've “lost their marbles,” they're jokingly suggesting they've lost their mind. If you describe something as “marbled,” like marbled meat or a marbled notebook cover, you mean it has swirling patterns similar to the stone.
