The artwork on stone is a combination of carving, inlaying engraving, sculpture and undercut (art of making multi layered decorative items out of one single piece of stone, hollowed from inside). Designs are made by cutting the stone and varying fine patterns on it. In fact, stonecutters and sculptors work hand in hand. The base material of work is marble, gorara soapstone and occasionally cuddapah. Marble is brought from the quarries of Makarana, Rajasthan. The choicest work from Agra can be seen in black and white marble from Rajasthan, or Alabaster of Italy, with semi precious materials such as Cornelian, Malachite, Lapis Lazuli, Mother of Pearl, Onyx Agate and Shazar laid into it. Use of inexpensive shells instead of semi precious stone make for reasonably priced gift items. The famous inlay work of Agra reflects the mosaic work used in Taj Mahal and Fatehpur Sikri. At present, this work is limited and enjoys an exclusive foreign demand.
