Solitaire Diamond and Gold Antique Art-Deco Ring

This solitaire diamond ring was actually once upon a time a men's shirt stud. The single, old cut diamond, is set within a 9k gold setting.  Old cuts date from a time when each diamond was hand cut in day light and according to the diamond's best qualities, as opposed to today's diamonds which are classified to meet the standard of a cut which is scientifically calculated to allow the maximum refraction of light within the stone. The diamond within its setting is salvaged from a turn-of-the-century shirt stud, which would have been worn in a men's shirt, and the band is a reproduction of a Victorian ring band cast in recycled 10k yellow gold. The setting and the diamond it contains date back to a wonderful time in antique jewelry, approximately a century or more ago when Victorian styles were giving way to more modern and streamlined motifs.  Settings and galleries were designed most often in elegant combinations of odd numbers--featured alone, as in this solitaire,  or in three's and
