Roberto Coin Cento O Diamond Set Ring

Roberto Coin Cento O ring set with a fine quality round brilliant cut Diamond weighing approximately 0.50 carats rub-over set in the centre.  The open circle is pave set with 2 rows of round brilliant cut Diamonds all mounted in 18 carat White Gold.  The signature ruby is set inside the band.  The outer diameter of the circle measures 19mm. Marked ''ROBERTO COIN CENTO'' with its signature ruby set inside the shank and 18ct and Italy stamps. UK finger size ''L 1/2'.

With 100 facets, almost double of a standard cut, each Cento diamond captures and reflects the light through a process which is much longer and more complicated than that used with other diamonds. The result is a veritable kaleidoscope of lights in a floral pattern defined by the shape of the 100 facets.
