Victorian Cushion Cut Sapphire Engagement Ring Rose Gold.  This Victorian engagement ring features a .63 carat cushion cut sapphire with 1.00 carats of round cut diamonds set in 14 karat yellow gold with a 14 karat rose gold band. This ring is a different take on the classic halo design through its use of two metal tones and very large diamonds in the halo. The dark blue sapphire looks amazing with its ten yellow gold prongs contrasting it and the diamonds surrounding it. The simple rose gold band meeting the yellow gold crown basket is yet another aspect that will set this Victorian beauty apart.
