     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to the drawings and first to  FIG. 1 , there is shown a ring  20  that is annular and which extends about an axis  21 . The ring has an opening  22 , and includes an annular band  24  that is circular in this example and which extends about the opening. The band comprises an upper shank  26  and a lower shank  28 , each of which is semi-circular in shape. The band  24  of the ring includes an inner surface, in this example an annular inner surface  27  in communication with the opening  22  and an outer surface, in this example an annular outer surface  29 . The ring has a depth D which extends between the inner and outer surfaces of the band. 
     A precious stone  30  couples to the upper shank at a top  32  of the ring. The ring  20  has a bottom  34  spaced from the top thereof and a pair of spaced-apart sides  36  and  38  which extend between the bottom and top thereof. The ring has a first annular end  40  and a second annular end  42  spaced-apart from the first annular end. The band  24  of the ring  20  has a ring width which extends between the annular ends  40  and  42  of the ring. 
     As seen in  FIG. 1 , there is provided a ring guard or ring sizing insert  44 , which may also be referred to as an adapter assembly for effectively modifying the ring size of ring  20 . As seen in  FIG. 2 , the insert includes a pair of elongate members  46  and  48 . Each of the elongate members is shaped to partially extend about the opening  22  of the ring  20 , as seen by elongate member  48  in  FIG. 1 , and extend substantially in parallel with the annular ends  40  and  42  of the ring  20 . The elongate members  46  and  48  are rigid and may be made of plastic, such as clear plastic, or metal, for example, such as gold, silver, platinum or stainless steel. These types of materials are examples only and are not strictly required, and the elongate members may be made of other materials in other embodiments. 
     The elongate members include finger-abutting, inner peripheral edges disposed within and extending along the opening of the ring. This is seen in  FIG. 1  by inner peripheral edge  52  for elongate member  48  and by inner peripheral edge  50  for elongate member  46  seen in  FIG. 2 . As seen in  FIG. 1 , the inner peripheral edges are generally straight and chord-like in lateral profile in this example and extend generally in a direction which is perpendicular to the axis  21  of the ring  20 . As seen in  FIG. 2 , each of the inner peripheral edges  50  and  52  of the elongate members  46  and  48  is arcuate-shaped in cross-section. 
     The elongate members include ring-abutting, outer peripheral portions as seen in  FIG. 1  by outer peripheral portion  56  for elongate member  48  and by outer peripheral portion  54  for elongate member  46  seen in  FIG. 2 . As seen in  FIG. 1 , the outer peripheral portions of the elongate members are spaced-apart from the inner peripheral edges  50  and  52  of the elongate members. Each of the outer peripheral portions  54  and  56  has a radius of curvature which is substantially similar to the radius of curvature of the annular outer surface  29  of the ring  20  seen in  FIG. 1  in this example. The outer peripheral portions of the elongate members are arcuate-shaped in lateral profile in this example. 
     As seen in  FIG. 2 , the outer peripheral portions  54  and  56  of the elongate members  46  and  48  include catches  58  and  60 , respectively. Each of the catches is C-shaped in cross-section in this example. The catches  58  and  60  face each other, and are shaped to at least partially extend about a portion of the band of the ring, as seen in  FIG. 1  by catch  60  extending about portion  62  of band  24  of ring  20 . The catches are positioned to extend outwards from the annular inner surface  27  of the ring  20  to and past the annular outer surface  29  of the ring. 
     Referring to  FIGS. 1 and 2 , catches  58  and  60  include arc-shaped, inner portions  63  and  64 , respectively, shaped to abut the annular inner surface of the ring seen in  FIG. 1 . As seen in  FIG. 2 , catches  58  and  60  include arc-shaped, circumferentially-extending lateral portions  65  and  66 , respectively, which extends across the depth D of the ring  20  as seen in  FIG. 1 . Referring to  FIG. 2 , catches  58  and  60  include arc-shaped outer portions  67  and  68 , respectively, which extend across part of and in the direction of the width of the ring. The inner portions  63  and  64  and outer portions  67  and  68  of the catches  58  and  60  extend in parallel with each other in this example. The lateral portion  65  of the catch  58  couples to and extends between portions  63  and  67 . The lateral portion  66  of the catch  60  couples to and extends between portions  64  and  68 . 
     Referring to  FIG. 2 , the catches  58  and  60  form and define channels  59  and  61 . The channels are arc-shaped in this example, as seen in  FIG. 3  by channel  61 . Channel  59  is shaped to receive and extend along a portion of the first annular end  40  of band  24  of ring  20  seen in  FIG. 1 , and channel  61  is shaped to receive and extend along an adjacent portion of the second annular end  42  of the band of the ring. 
     Each of the elongate members  46  and  48  includes a laterally-extending planar portion which extends between its inner and outer peripheral portions. This is seen in  FIG. 1  by planar portion  72  for elongate member  48  in  FIG. 1  and planar portion  70  for elongate member  46  seen in  FIG. 2 . Referring to  FIG. 2 , inner surfaces  74  and  76  of the planar portions  70  and  72  of the elongate members  46  and  48  face each other, and outer surfaces  78  and  80  are spaced-apart from said inner surfaces  74  and  76 , respectively. As seen in  FIGS. 1 and 2 , the planar portions of the elongate members  46  and  48  each comprise inner planar portions or regions  81  and  83 , respectively. The regions are circular segments in lateral profile spanning the opening  22  of the ring  20  in this example, as seen in  FIG. 1  via region  81  of planar portion  72  of elongate member  48 . 
     As seen in  FIG. 3 , elongate member  48  includes at least one, and in this example a pair of recesses, in this example sockets  82  and  84  which are generally in the shape of cylindrical bores in this example. The sockets extend into the planar portion  72  thereof, from the inner surface  76  towards the outer surface  80  of the planar portion seen in  FIG. 2 . Referring to  FIGS. 2 and 4 , elongate member  46  includes at least one, and in this example a pair of outwardly extending protrusions  86  and  87 . The protrusions are generally cylindrical in shape in this example. The protrusions  86  and  87  couple to and extend outwards from the inner planar portion or region  81  of elongate member  46 . Sockets  82  and  84  are shaped to selectively receive the protrusions  86  and  87 . In this manner, the elongate members  46  and  48  are shaped to interference fit together, with the inner surfaces  74  and  76  of the planar portions  70  and  72  of the elongate members  46  and  48  abutting each other when the elongate members are so coupled together. The elongate members are thus selectively connectable together. The peripheral portions  54  and  56  of the elongate members  46  and  48 , when coupled together, form a receptacle  88  through which a portion of the band of the ring extends. In this manner and referring to  FIG. 1 , the insert  44  selectively couples to the ring  20 . The elongate members  48  so shaped function to reduce the effective size of the opening  22  of the ring, thereby enabling the ring to fit onto a smaller-sized finger, toe or the like. 
       FIG. 5  shows a ring sizing insert  44 . 1  according to a second aspect. Like parts have like numbers and functions as the insert  44  shown in  FIGS. 1 to 4  with the addition of decimal extension “0.1”.

This may result in an insert  44 . 3  that accommodates rings of greater width, for example. 
       FIG. 8  shows a ring sizing insert  44 . 4  according to a fifth aspect. Like parts have like numbers and functions as the insert  44  shown in  FIGS. 1 to 4  with the addition of decimal extension “0.4”. Insert  44 . 4  is the same as described for insert  44  shown in  FIGS. 1 to 4  with the following exception. The finger-abutting peripheral portions  50 . 4  and  52 . 4  of the elongate members  46 . 4  and  48 . 4  when coupled together collectively form an arcuate shape in cross-section in this example. 
       FIG. 9  shows a ring sizing insert  44 . 5  according to a sixth aspect.

     Insert  44 . 9  includes a fastener, in this example a bolt  116 . The bolt is shaped to further couple the elongate members  46 . 9  and  48 . 9  together, with the bolt extending through aperture  112  of elongate member  46 . 9  and threadably engaging with elongate member  48 . 9  via threaded aperture  114 . 
       FIGS. 22 to 23  show a kit  117  of ring sizing inserts  44 . 9 ,  44 . 10 ,  44 . 11  and  44 . 12  for effectively reducing the ring size of a plurality of rings  20 . 9 ,  20 . 10 ,  20 . 11  and  20 . 12  of varying widths W, W. 10 , W. 11  and W. 12  seen in  FIG. 23 . 
     Elongate members  46 . 9 ,  46 . 10 ,  46 . 11  and  46 . 12  are substantially the same as each other, with like parts having like numbers and the substitution of an incrementally higher decimal extension number. Elongate members  48 . 9 ,  48 . 10 ,  48 . 11  and  48 . 12  are substantially the same, with like parts having like numbers and the substitution of an incrementally higher decimal extension number, with the following exceptions. 
     Referring to  FIG. 22 , inner planar portion  83 . 10  and inner peripheral edge  52 . 10  of elongate member  48 . 10  are larger in a direction extending from the outer surface  80 . 10  of the planar portion  72 . 10  to the inner surface  76 . 10  of the planar portion, compared to the inner planar portion  83 . 9  and inner peripheral edge  52 . 9  of elongate member  48 . 9 . As seen in  FIG. 23 , elongate member  48 . 10  may thus fit ring  20 . 10  having a width W. 10  that is greater than that of ring  20 . 9 . 
     As seen in  FIG. 22 , inner planar portion  83 . 11  and inner peripheral edge  52 . 11  of elongate member  48 . 11  are larger in a direction extending from the outer surface  80 . 11  of the planar portion  72 . 11  to the inner surface  76 . 11  of the planar portion, compared to the inner planar portion  83 . 10  and inner peripheral edge  52 . 10  of elongate member  48 . 10 . As seen in  FIG. 23 , elongate member  48 . 11  may thus fit ring  20 . 11  having a width W. 11  that is greater than that of ring  20 . 10 . 
     Referring to  FIG. 22 , inner planar portion  83 . 12  and inner peripheral edge  52 . 12  of elongate member  48 . 12  are larger in a direction extending from the outer surface  80 . 12  of the planar portion  72 . 12  to the inner surface  76 . 12  of the planar portion, compared to the inner planar portion  83 . 11  and inner peripheral edge  52 . 11  of elongate member  48 . 11 . As seen in  FIG. 23 , elongate member  48 . 12  may thus fit ring  20 . 12  having a width W. 12  that is greater than that of ring  20 . 11 . 
       FIGS. 24 to 25  show a ring sizing insert  44 . 13  according to a fourteenth aspect. Like parts have like numbers and functions as the insert  44 . 9  shown in  FIGS. 20 to 21  with decimal extension “0.13” replacing decimal extension “0.9” and being added for numbers not previously having decimal extensions. Insert  44 . 13  is the same as described for insert  44 . 9  shown in  FIGS. 20 to 21  with the exception that the insert includes a fastener in the form of a rivet  116 . 13 . The elongate members  46 . 13  and  48 . 13  are thus further riveted together via said rivet. 
     As seen in  FIG. 25 , the rivet  116 . 13  includes an elongate portion, in this example a shaft  118  which extends through apertures  112 . 13  and  114 . 13  of elongate members  46 . 13  and  48 . 13 , respectively. The rivet has a pair of spaced-apart protuberances  120  and  122  which couple to and extend radially outwards from opposite ends  124  and  126  of the shaft. The protuberances abut outer surfaces  78 . 13  and  80 . 13  of the planar portions  70 . 13  and  72 . 13  of the elongate members  46 . 13  and  48 . 13  after the protrusions  86 . 13  and  87 . 13  of elongate member  46 . 13 , seen in  FIG. 24 , are received within sockets  82 . 13  and  84 . 13  of elongate member  48 . 13 . The rivet  116 . 13  functions to inhibit separation of the elongate members thereby. 
       FIGS. 26 to 27  show a ring sizing insert in this example a ring coupler  44 . 14  according to a fifteenth aspect. Like parts have like numbers and functions as the insert  44 . 9  shown in  FIGS. 20 to 21  with decimal extension “0.14” replacing decimal extension “0.9” and being added for numbers not previously having decimal extensions. Coupler  44 . 14  is the same as described for insert  44 . 9  shown in  FIGS. 20 to 21  with the following exceptions. 
     Referring to  FIG. 26 , channel  59 . 14  of elongate member  46 . 14  is shaped to receive and extend along a portion  128  of a first annular end  130  of a first ring  132 . The second annular end  134  of the first ring abuts the first annular end  40 . 14  of a second ring  20 . 14 . Channel  61 . 14  of elongate member  48 . 14  is shaped to receive and extend along portion  62 . 14  of annular end  42 . 14  of the second ring. The elongate members  46 . 14  and  48 . 14  are selectively connectable together for coupling together the rings  132  and  20 . 14 , and are further shaped to partially extend within the opening of the rings. 
     Inner planar portion  83 . 14  and inner peripheral edge  52 . 14  of elongate member  48 . 14  are larger in a direction extending from the outer surface  80 . 14  of the planar portion  72 . 14  to the inner surface  76 . 14  of the planar portion, compared to the inner planar portion  83 . 14  and inner peripheral edge  52 . 14  of elongate member  48 . 14 . Inner planar portion  83 . 14  and inner peripheral edge  52 . 14  of elongate member  48 . 14  extend across the width W. 14  of ring  20 . 14  and partially across the width W. 14 ′ of ring  132  in this example. 
     It will be appreciated that many variations are possible within the scope of the invention described herein. For kit  117  seen in  FIGS. 22 and 23 , instead of elongate members  46 . 9 ,  46 . 10 ,  46 . 11  and  46 . 12 , the kit may comprise only elongate member  46 . 9 , for example. It will also be understood by someone skilled in the art that many of the details provided above are by way of example only and are not intended to limit the scope of the invention which is to be determined with reference to at least the following claims.
