Grey Spinel Engagement Ring w/ Diamond Accents in White Gold.  This modern engagement ring features a .93 carat round cut grey spinel which is bead set in 14 karat white gold and adorned with .20 carats of diamonds. The accent diamonds are all set on one side of the band surrounding the center stone and the settings imitate a sharp, almost marquise shape despite them actually being round diamonds. These design features all combine to create a unique looking asymmetrical ring with an uncommon colored center stone.
