[0030] As shown in FIG. 1, FIG. 2, and FIG. 3, a bare diamond waist code mirror of this embodiment includes a seat body 10, an observation mechanism, a first focusing mechanism 4, a second focusing mechanism 5, and a diamond clip 3.

[0031] In general, clamping cavities (A, B) are formed in the seat body 10, and a clamping mechanism is installed in the clamping cavities. The observation mechanism includes a gearbox 6 and a magnifying lens assembly 8 that enables eye-level observation.

[0032] The gearbox 6 is movably installed onto the back part of the seat body 10 in a front-back direction, and achieves forward and backward fine adjustment for displacement and focusing through a gear in a box body meshed with the first focusing mechanism 4. The magnifying lens assembly 8 is provided with a second rack plate 812, is thus installed onto the gearbox 6 in an upward and downward moving manner through the second rack plate 812 extending into the box body, and achieves vertical fine adjustment of displacement and focusing through a gear of the second rack plate 812 meshed with the second focusing mechanism 5. The diamond clip 3 clips a diamond or gem 95, and is rotatably fixed on the clamping mechanism (21, 25), and the diamond clip 3 is rotated to achieve circumferential fine adjustment in an own circumferential direction and focusing of the bare diamond or gem 95 thereon. Through fine adjustment of displacement in the above three dimensions and focusing, the magnifying lens assembly 8 is focused for observing the code of the diamond or gem 95.

[0033] Specific embodiments are introduced as follows:

[0034] Referring to FIG. 5 together, the seat body 10 includes a first outer shell 11, a second outer shell 12, a first structural inner shell 15, and a second structural inner shell 18. The first outer shell 11 and the second outer shell 12 close in to form a seat body outer shell. The first outer shell 11, the second outer shell 12, and the first structural inner shell 15 close in at the upper part of the seat body to form the upper clamping cavity B; and the first outer shell 11, the second outer shell 12, and the second structural inner shell 18 close in at the bottom of the seat body 10 to form the lower clamping cavity A. That is, the clamping cavity includes the upper clamping cavity A and the lower clamping cavity B.

[0035] Notches are provided on the back parts of the first outer shell 11 and the second outer shell 12 to form an entrance-exit window D of the gearbox 6. After the middle parts of the first outer shell 11 and the second outer shell 12 are both concavely assembled, an operating space C that is used for operating and rotating the diamond clip with a hand is formed. With the upper clamping cavity A and the lower clamping cavity B in the seat body 10, the middle part of the seat body 10 is concave to form the operating space C.
