Description:
FIELD OF THE INVENTION  
       [0001]     This invention relates to writing instruments, particularly pens or the like.  
       BACKGROUND OF THE INVENTION  
       [0002]     Writing instruments decorated with gems, like a pen mounted with a piece of diamond, may act as luxury or collector items. Although gems may be appreciated with the normal eye, one who appreciates the finer qualities of a gem in terms of the color and may prefer to have a tool for viewing the gem, like a magnifying glass instrument. However, such a viewing tool may be relatively inconvenient to be carried separately.  
       OBJECTS OF THE INVENTION  
       [0003]     Therefore, it is an object of this invention to resolve at least one or more of the problems as set forth in the prior art. As a minimum, it is an object of this invention to provide the public with a useful choice.  
       SUMMARY OF THE INVENTION  
       [0004]     Accordingly, this invention provides a writing instrument having a first and a second portion, and a gem mounted on said writing instrument, and a loupe removably contained in the first portion.  
         [0005]     Preferably, the gem is a piece of diamond. Optionally, the gem is mounted on the first portion. More preferably, the gem is mounted at one end of the first portion. 
     
    
     BRIEF DESCRIPTION OF THE DRAWINGS  
       [0006]     Preferred embodiments of the present invention will now be explained by way of example and with reference to the accompanying drawings in which:  
         [0007]      FIG. 1  shows a writing instrument of this invention and its exploded views; and  
         [0008]      FIG. 2  shows the views of a piece of diamond viewed by the loupe contained in the writing instrument of this invention.  
     
    
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0009]     This invention is now described by way of example with reference to the figures in the following paragraphs. List  1  is a part list so that the reference numerals in the figures may be easily referred to.  
         [0010]     Objects, features, and aspects of the present invention are disclosed in or are obvious from the following description. It is to be understood by one of ordinary skill in the art that the present discussion is a description of exemplary embodiments only, and is not intended as limiting the broader aspects of the present invention, which broader aspects are embodied in the exemplary constructions.  
         [0011]      FIG. 1  shows the writing instrument  10  of this invention, and its components in its exploded view. The writing instrument  10  as shown in  FIG. 1  is in the form of ball point pen, but of course other forms of writing instruments are possible, like a fountain pen or mechanical pencil.  
         [0012]     The pen  10  may be divided a first portion  30  and a second portion  40 . These portions generally are separable from each other but this is not a must for this invention. The second portion  40  may contain the filler  50  of the ball point pen. The first portion  30  may be further divided into three sections, a crown  32  at one end attached to a detachable upper barrel  34 , which is in turn connected to a lower barrel  36 . The viewing instrument or the loupe  60  is contained in the detachable upper barrel  34 . However, the structure of the first portion  30  as shown in  FIG. 1  is merely an example, and other configurations are possible. For example, the first portion  30  may be formed by only the crown  32  and the upper barrel  34  containing the viewing instrument  60 , which may be directly connected with the second portion  40 .  
         [0013]     The gem  38  may be mounted on the crown  32  at one end of the first portion  30 . It is possible to mount the gem  38  onto other portions of the writing instrument  10 , for example, the body of the firs barrel  34 .  
         [0014]     The viewing instrument  60  as shown in  FIG. 1  is a loupe particularly if the gem is a piece of diamond. Loupe is a simple brilliance assessment device with a magnifying lens, say 6.5× or 10×, which can offer a qualitative assessment of symmetry. The loupe  60  may comprise a semi-transparent loupe eye piece  62  to shield filter excess light, a loupe lens  64 , and a loupe cylinder  66 . The loupe  60  should of course be sized to be contained in the first portion  30 . The viewing instrument  60  can also be used independently to view other gems.  
         [0015]     Some proportions of diamonds when cut with perfect symmetry display  8  hearts and 8 arrows, as shown in  FIG. 2 . A pleasing distribution of black gives an observer a nice display of scintillation as the stone is rocked from side to side. The 8 hearts pattern can viewed by the loupe from the pavilion side of the diamond while the 8 Arrows are visible using the loupe from the top of the Hearts and Arrows Diamond.  
         [0016]     The writing instrument  10  of this invention may allow the user to have a handy and suitable tool for viewing the gem mounted on the writing instrument  10 . The may enhance the value of the writing instrument  10 .  
         [0017]     While the preferred embodiment of the present invention has been described in detail by the examples, it is apparent that modifications and adaptations of the present invention will occur to those skilled in the art. Furthermore, the embodiments of the present invention shall not be interpreted to be restricted by the examples or figures only. It is to be expressly understood, however, that such modifications and adaptations are within the scope of the present invention, as set forth in the following claims. For instance, features illustrated or described as part of one embodiment can be used on another embodiment to yield a still further embodiment. Thus, it is intended that the present invention cover such modifications and variations as come within the scope of the claims and their equivalents.
