摘要： Disclosed are a new diamond cutting method and a diamond shape or proportion giving an increased brightness and different brilliant colors to the cut jewel. A piece of diamond having a crown or bezel and a pavilion converging up and down from its girdle is prepared; the table of the crown is cut into a regular polygon having straight sides of an integer multiple of three; star facets, upper-main facets and paired upper-girdle facets are formed on the oblique annular surface between the polygonal table and the girdle; and lower-girdle facets and lower-main facets are cut on the pavilion. The height of the diamond piece is approximately 64% of the diameter of the girdle; the height of the crown is approximately 15.7%; the height of the pavilion is approximately 48.3%; and the largest width of the girdle is approximately 1.2 to 1.4%. The angle formed between the ridge of the crown and the ridge of the pavilion is approximately 77 degrees.

摘要： A method for preparing a diamond having a six-pointed-star shaped girdle comprising: (1) providing a round diamond; and (2) grooving six equally spaced, equally-sized triangularly-shaped 120° angled grooves in the girdle of the round diamond. Also disclosed is a grooving machine comprising a dop, wherein the dop may be rotated between six equally-spaced stops.

摘要： A scribe body (A) includes an abutment member (30) and a vibration generating member (40) for applying vibrations to the abutment member (30). The scribe body (A) is connected to a support portion (6) of a slide mechanism (3) through a vibration damping member (7). Two pairs of vibration damping members (7) are vertically spacedly arranged. The vibration damping members (7) of each pair are arranged on the left and right sides of the scribe body (A). By relatively moving the abutment member (30), which is pressed against a surface of a workpiece by its own weight of the scribe body (A), along the surface of the workpiece while applying vibration, which are generated by the vibration generating member (40), to the abutment member (30), a scribe line is formed in the surface of the workpiece. Vibration of the scribe (A) is damped by the vibration damping member (7).

摘要： A method and an apparatus for cutting a wafer from a crystalline ingot, by directing a stream or streams of etching gas at the crystalline ingot in a vacuum. Waste in cutting can be greatly minimized and the work environment can also be kept clean. Further, excellent surface smoothness can be realized on the cut wafers.
