Precious stone setting

A precious stone setting comprising:

• (a) a shank body with a circumferential edge having a recessed cavity with internal wall corresponding to a first and a second recessed edge extended upwardly, the upper section of the second recessed edge being mounted with a mounting rim such that the lower section of the first recessed edge is formed into a groove;
• (b) an external rim being a hollow rim with an inner edge correspondingly mounted with two shaft hole with external circumferential edge at the center of the shaft hole being mounted with two externally protruded branch shafts and the two branch shaft being insertable into the groove of the shank body to form into a combination which is rotatable and pivotable;
• (c) a collet having an upward opened cavity for a precious stone, the circumferential wall of the cavity being provided with two corresponding perpendicularly extended gaps and the circumferential edge of the collet being mounted with two outwardly protruded branch shafts which respectively extend into the two shaft holes at the inner edge of the external rim to form into another free-to-pivot combination;
• whereby by utilizing the pivotal axis of the branch shaft of the collet and the external nm being perpendicularly, and the branch shaft of the external rim is rotatable along the groove of the shank body, the sloping angle of the precious stone changes according to the change of position of the shank body to provide an aesthetic appearance.
