typically at a location adjacent that of the pin 39 s magnet 122 the pin 42 f is thus held in the ring when in the assembled situation yet the pin can be readily removed for allowing a different setting arrangement to be used fig1 illustrates an attachment mechanism 130 wherein the ring has a vertical hole 20 g with a pin 42 g typically inserted in a direction entering via the inner surface 12 of the ring the pin 42 g may have a head 44 g designed to correspond to a depression 132 in the hole 20 g so that the inner surface 12 is smooth and comfortable for a wearer 39 s finger furthermore the pin 39 s head 44 g is typically flat or slightly contoured for the same reason the pin 42 g has been shown in the form of a screw and thus there is shown a solitaire setting 22 g with a threaded bore 134 fig1 illustrates another attachment mechanism 140 of a somewhat different type than those previously described here the mechanism 140 comprises a clasp 142 which can be attached typically to the solitaire setting 22 to close the clasp 142 assemble the setting s on the ring.
