Early 20th century circa 1915 dates this wonderful enamel ring with sweet rose motif.  The setting is made of 12k gold with black enameled recesses highlighting a floral swirl.  This is a very feminine version of cigar band rings that were popular at the time.  The oval rose cabachon stone is bezel set and the band is marked with the C&C logo for the Clark and Coombs Co. of Providence, RI whose history in jewelry making goes back to 1875.  The maker's mark that is stamped inside of this ring made of initials set inside of triangles, dates this ring to the post 1915 era.  The ring is a size 6 3/4.   SORRY! THIS ITEM HAS ALREADY BEEN SOLD.
