SOLUTION: An attachment frame is formed in a downward narrowing cylinder shape, is provided with erecting parts 4 in its upper part and holds a jewel 10 so that lay-in parts 15 formed at the inner side of the erecting parts 4 are laid-in to the inside of slits 5 provided in the pavilion parts of the jewel 10 which is stored inside the attachment frame. The slits 5 are formed just under girdle part 13 on at least two opposing sides of the jewel 10. Each slit 5 has a V-shaped cross section and its upper surface is formed in parallel with or more upward than the girdle part 13 of the jewel 10.
