Marble inlay floor design, also known as "Pietra Dura" (Italian for "hard stone") or "Parchin Kari" (Indian term), is an exquisite and ancient art form that involves embedding precisely cut and polished pieces of colored stones, often semi-precious, into a marble base to create intricate patterns and designs. This technique transforms a simple floor into a stunning work of art, adding a touch of luxury and timeless elegance to any space.
