In the early 20th century, to showcase the newly mined diamonds coming from South Africa and South America, the master jewelers decorated their handmade platinum rings with graceful and precise hand-engraved motifs, such as flowers, foliate and geometric patterns. This ring, sublime in its simplicity, is set with the original 1920's hand-cut squarish-shaped diamond weighing 3.06 cts., an exceptional example of the artistry and ingenuity that celebrated the new world of diamonds.
