I call this design "Sun & Moon". A .25ct. faceted Brazilian Rubellite Tourmaline & .05ct. diamond are bezel set in 18KY gold, soldered to rhodium plated textured silver. The top of the ring measures 3/8" X 5/8". It is ergonomically designed with a weighted euro shank so it does not flip flop from sided to side on your finger.  Diamond or other bands may be stacked with this ring. Ring size is 7 & 3/4. This ring is not sizeable, but I can make one to order-- in any size-- with stones of your choi Modern Ruby Diamond Ring, Modern Ruby Ring With Bezel Setting For Anniversary, Modern Multi-stone Diamond Ring, Unique Ruby Ring With Bezel Setting For Anniversary, Rubellite Tourmaline, 18k Gold Ring, Metal Work, Negative Space, Ring Ring
