Castellani® has selected this Ancient Roman Agate Intaglio for the "Cleopatra" Ring Setting. The intaglio dates to the 3rd to 7th Century. The intaglio is both black and white agate, which is a hard stone and very good for carving. The agate has two layers of color, black on the top and white at the bottom. The agate intaglio is solid and is one piece. The carver was able to use these two color layers to give dimension and detail. The Column and Angel on the left wings are white and the balance is all black. The Carver knew the material he/she was carving and used this to create this very unique scene. The intaglio shows two angels standing on either side of a column/pillar looking at the bust of a man on top of the pillar. The angels are female and male. The bust on the pedestal is of a male. The intaglio is set below the frame. The frame flairs out to a subtle point on the sides and has a flat surface. The "Cleopatra" ring design was a style that Castellani created in the 1860's and was inspired by Ancient Roman rings...
