Dat uses a hart bur to cut the seats for the stones. A seat is essentially a small notch that is carved into the inner surface of each prong.

When your gemstone is placed onto this seat, it helps to hold it firmly in place, preventing it from shifting or becoming loose over time. He then lowers the stones into the prongs using a wax dop and secures the prongs using pliers.

Dat then carefully shapes the prongs using a file, refining them to their final form. This step requires precision to ensure the prongs provide both strength and elegance—filing too much could weaken their support for the stone, while just the right amount ensures a secure and graceful setting.
