Oval Sapphire
The dazzling centerpiece of this ring is an oval blue sapphire, and it’s held in four platinum prongs that transition seamlessly out of the strands of the split shank below. The sapphire is set lengthwise across the band so that it’s inline with the finger when worn, and this helps give the ring a more balanced feel. Sapphire and Diamond Engagement Rings
Diamond Accents and Band Design
The band is flat and relatively wide at the bottom, although it does widen a bit more as it moves up the side. It splits just before the mid-point, with two thinner strands on either side running up to form the prongs of the center setting. The wider middle portion continues the original curve of the band, running directly under the oval sapphire and connecting to the same spot on the opposite side. One of a Kind Engagement Rings
This middle section is channel set with princess cut and baguette diamonds in an alternating pattern, and the 11 diamonds used together total exactly one carat. These provide a dramatic contrast, both in terms of color and shape, to the rich blue stone at the top, and their placement contributes greatly to the unique contemporary flair of the design.
