Presented here, an antique  ART DECÓ ring made in 18K yellow gold (no visible hallmarks, so therefore it has been professionally acid-tested), Platinum and natural diamonds. The ring is decorated with a total of eleven (11) natural diamonds, set in a Platinum base.  The main one is an old-european cut natural diamond, white commercial color and SI purity; it measures 4.50mm diameter, therefore its approximate weight in carats would be at least 0.25ct. This main diamond is "illusion" style set with six claws (see pictures, please).
  The other ten (10) natural diamonds are rose cut and are set in pavé style. They are decorating both ribbon, bow or loop   shaped sides of the main diamond (see pics, please). They measure between 1 and 2mm diameter, each.
 
Please refer to the pictures, they speak by themselves.
