Jewelry system

Abstract

A jewelry system includes an outer ring having an open shank and an aperture on either side of the shank, and an inner ring configured to be received within an aperture of the outer ring such that the outer ring and the inner ring are removably coupled to one another. The inner ring includes extending surfaces or protrusions at side points on opposite sides of its shank, near the base of the shank, which are configured to be seated within the apertures in the outer ring. The extended surfaces are located at approximately 5 o'clock and 7 o'clock on the inner ring and are configured prevent the movement of the inner ring with respect to the outer ring while the inner ring is coupled to the outer ring.

         7 . The jewelry system of  claim 1 , wherein the front portion and the rear portion each comprise a head, a left side shank, and a right side shank, each of the left side shank and the right side shank extend from the respective head towards a bottom portion of the outer ring. 
     
     
         8 . The jewelry system of  claim 7 , wherein the front portion and the rear portion of the outer ring are coupled to one another with a first base and a second base, the first base couples the left side shank of the front portion to the left side shank of the rear portion, and the second base couples the right side shank of the front portion to the right side shank of the rear portion. 
     
     
         9 . The jewelry system of  claim 8 , wherein the first base and the second base are located proximate the bottom portion of the outer ring at a distal end of the respective shanks, the distal ends of the right side shanks and the left side shanks being ends furthest from the respective head of the front portion or the rear portion. 
     
     
         10 . The jewelry system of  claim 7 , wherein distal ends of the left side shanks are spaced apart from distal ends of the right side shanks to form an opening between the respective shanks proximate the bottom portion of the outer ring. 
     
     
         11 . A jewelry system, comprising:
 an outer ring comprising:
 a front portion comprising a head, a left side shank, and a right side shank, wherein the left side shank and the right side shank extend from the head towards a bottom portion of the ring; and 
 a rear portion comprising a head, a left side shank, and a right side shank, wherein the left side shank and the right side shank extend from the head towards a bottom portion of the ring, wherein the rear portion is coupled to the front portion, and spaced from the front portion to form an aperture therebetween, and 
   an inner ring received within the aperture of the outer ring and being removably coupled to the outer ring, wherein the inner ring comprises a shank having a top portion and a bottom portion, a first protrusion and a second protrusion, each of the first and the second protrusions located proximate the bottom portion of the shank at opposite sides, wherein the first and the second protrusions are configured to engage corresponding portions of the outer ring to prevent movement of the inner ring with respect to the outer ring while the inner ring is coupled within the outer ring.   
     
     
         12 . The jewelry system of  claim 11 , wherein the first and second protrusions are configured to mitigate rotation of the inner ring with respect to an axis of rotation extending through centers of the outer ring and the inner ring. 
     
     
         13 . The jewelry system of  claim 11 , wherein the first protrusion and the second protrusion extend radially outward from the shank of the inner ring and are radially located at approximately 5 o'clock and 7 o'clock on the inner ring. 
     
     
         14 . The jewelry system of  claim 11 , wherein the first protrusion and the second protrusion extend radially outward from the shank of the inner ring, the first protrusion is located between 215 and 235 degrees from the top portion of the inner ring and the second protrusion is located between 125 and 145 degrees from the top portion of the inner ring.
