A technique for positioning a stone utilizes a pencil comprising a shaft having at one end a handle and at the opposite end supporting means adapted to hold a stone upon the application of a closing force thereto. The shaft has apparatus for adjusting the length thereof, and a housing fitted over the shaft between the ends thereof in a manner allowing the shaft to be frictionally rotated therein. The housing has apparatus for applying the closing force, disposed at one end thereof adjacent the supporting means, and is adapted to provide the closing force when the shaft is moved longitudinally along the housing.
