The elegance of linear geometry is a hallmark of classic Art Deco design. This exceptional example by René Boivin features a well saturated step-cut aquamarine accented by pierced scrolling shoulders set with single-cut diamonds mounted in platinum. The ring was produced under the direction of Boivinâs head designer Juliette Moutard; creator of the legendary starfish brooch; perhaps the Houseâs most well-known jewel. Signed René Boivin with French assay mark Circa 1935
