This technique, often associated with traditional Indian art, especially in structures like the Taj Mahal, involves meticulous cutting and fitting of the inlaid pieces, showcasing a high level of craftsmanship. It can be used in various applications, including tabletops, flooring, and wall decorations, adding elegance and sophistication to the overall aesthetic.
