CROSS REFERENCE TO RELATED APPLICATION 
     This application claims the benefits of the Taiwan Patent Application Serial Number 099127386, filed on Aug. 17, 2010, the subject matter of which is incorporated herein by reference. 
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a method of fabricating diamond-emulating frame structure and a diamond-emulating frame structure provided by the same, more particularly, to a method of fabricating diamond-emulating display frame structure and a diamond-emulating display frame structure provided by the same. 
     2. Description of Related Art 
     According to the related arts, Taiwan issued patent no. 363240 disclosed a cosmetic case having a decorative region on the outer surface of the case, the decorative region has plural concaves regularly arranged, the concaves are coated with paillettes, sparkle gold powders or fluorescence powders by a physical or chemical method, and some decorative items (e.g. artificial diamond or diamond-emulating plastics) are received in the concaves respectively. Therefore, due to those paillettes, fluorescence powder, or the decorative items, the cosmetic case has an attractive exterior and attracts the consumers&#39; attention. The sparkle gold powders or fluorescence powders coated on the surface of the concaves may serve as a base layer to load those decorative items and enhance the reflectivity of the decorative region. However, those sparkle gold powders or fluorescence powders may only serve as the base layer, and cannot possess decorative ability independently. Also, the image or light reflected by those sparkle gold powders or fluorescence powders is blurred.

     drying the decorative frame  20 ; and 
     combining the decorative frame  20  with the display frame module  30  via the connecting part  50 . 
     First Embodiment 
     With reference to  FIGS. 1 ,  2 ,  3 ,  4 , and  5 , a diamond-emulating display frame structure  1  of the present invention comprises: a display frame module  30 ; a decorative frame  20 ; and a decorative member  10 . 
     First, a decorative frame  20  is provided, in which the decorative frame  20  has plural concaves  202  arranged in order and separated via plural partitions  2020 . The concave  202  has a curved shape and thus forms a curved concave  2022 . 
     Then, a de-waxing layer  2010  is formed on the surface of the partitions  2020  of the decorative frame  20  by a screen printing method, and a de-waxing region  201  is thus formed between the curved concaves  2022 , as shown in  FIG. 3 . 
     After that, an adhesive layer  2041  is spray coated on the whole surface of the decorative frame  20  that has printed with the de-waxing layer  2010 , and then a reflective material layer  40  is spray coated on the surface of the decorative frame  20  that has coated with the adhesive layer  2041 . Herein, the reflective material layer  40  is a sparkle gold powder layer. 
     Last, part of the reflective material layer  40  that locates at the de-waxing region  201  is removed to expose the partitions  2020 . Then, the decorative frame  20  is dried at a drying room, and the obtained decorative frame  20  is shown in  FIG. 5 . 
     Reference with  FIG. 1 , the decorative frame  20  that is coated with the reflective material layer  40  is combined with the display frame module  30 , and then the decorative member  10  made of a transparent material is set on the decorative frame  20  and is fixed with the display frame module  30 . Therefore, the diamond-emulating display frame structure of the present invention is able to enhance diamond-emulating visual effect without using other decorative items such as artificial diamond or diamond-emulating plastics. 
     In the present embodiment, the sparkle gold powder of the reflective material layer  40  can be a thermoplastic material made by vacuum-sputtering an aluminum layer on a base and following with dyeing and fine-cutting, in which the material of the base can be selected from polyethylene terephthalate (PET) and polyvinylchloride (PVC), the diameter (i.e. the particle size) of the base can be in a range of 0.004 mm-3.0 mm, the shape of the base can be square, hexagon, a heart-shape, a star-shape, a crescent-shape, or a snowflake-shape, and the color of the base can be gold, silver, multi-color (e.g. rainbow color or any color combination), or pearl luster. 
     Second Embodiment 
     The diamond-emulating display frame structure of the second embodiment is similar with that of the first embodiment, except the curved concave  2022  is replaced with a trapezoid concave  2024  and the sparkle gold powder layer is replaced with a pearl luster powder layer having a smaller particle size. 
     Reference with  FIGS. 6 and 7 , the trapezoid concave  2024  in the second embodiment has four inclined walls and a flat floor. 
     According to the second embodiment, the sparkle gold powder in the sparkle gold powder layer is a mica powder coated with titanium dioxide, which has a color of silver white, a density of 3 g/cm, and a particle size of in a range of 3 μm-150 μm. 
     In the second embodiment, the reflective material layer  40  can be selectively made of an aluminum sputtered layer for replacing the pearl luster powder layer. 
     Third Embodiment 
     Reference with  FIGS. 8 and 9 , the diamond-emulating display frame structure of the third embodiment is shown, which has a first decorative sub-frame  203  and a second decorative sub-frame  204  coupling with each other, and thus a spacing  2036  is provided between the first decorative sub-frame  203  and the second decorative sub-frame  204 . The first decorative sub-frame  203  is made of a transparent material. A solution layer  60  comprising pearl luster powder is filled in the spacing  2036  and flowing therein, and therefore a different visual effect can be obtained. 
     Herein, the particle size of the pearl luster powder of the solution layer  60  is smaller than that of the second embodiment. The walls of the upper concave  2034  and the lower concave  2035  are curved inclined walls. 
     As mentioned above, the method of fabricating diamond-emulating display frame structure and a diamond-emulating display frame structure provided by the same of the present invention utilize sparkle gold powder layer or pearl luster powder as well as reflections at different angels from the display frame to enhance diamond-emulating visual effect without using other decorative items such as artificial diamond or diamond-emulating plastics. Therefore, the manufacturing cost of the diamond-emulating display frame structure can be largely decreased. 
     Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
