This modern diamond and sapphire engagement ring is a lovely example of bringing back Art Deco designs.  The center .51 carat round brilliant is bezel set in platinum.  The center diamond is accented by a sapphire halo completed in .35 carats of French cut sapphires.  The sapphires add a lovely cast of blue on to the center diamond.  The shoulders of the ring feature round diamonds flanking the sapphire halo.
