IMPLEMENT FOR OBSERVING JEWEL OR ACCESSORY AND METHOD FOR PICKING UP IMAGE OF DIAMOND OR ACCESSORY WITH DIAMOND, USING THE IMPLEMENT

摘要

PURPOSE: To enable simultaneous observation or photographing of a precious metal part whereon a diamond is mounted or other jewelry set around the diamond, with the characteristic pattern of the diamond due to a reflected light therefrom. ;CONSTITUTION: An implement which is a tubular body 1 being made up of a lower tubular part 2 and an upper tubular part 3 provided continuously to the upper part of the lower tubular part, and having the upper and lower ends opened 4 and 5, of which the inner surface of the lower tubular part 2 has a chromatic color, of which the upper tubular part 3 is made of a translucent material or a material transmitting light moderately and of which the lower tubular part 3 is so constructed that a line connecting the center of the lower end part thereof and the upper edge part has an angle of 10° to 25° to the axial line of the lower tubular part 2, is used. At the central part of the lower end part of the lower tubular part 2 making up this implement, a diamond B is positioned in a state wherein the lower edge part of the crown of the diamond B coincides substantially with the height of the lower edge part of the lower tubular part 2, and the diamond or an accessory with the diamond is observed or photographed from above the upper tubular part 3 through the inside of the tubular body.;COPYRIGHT: (C)1994,JPO&Japio
