Three-stone Setting
At the center of this ring is a 1.50 carat round brilliant cut diamond in a four prong platinum setting. The prongs are straight, and they come up at an angle that perfectly complements the shape of the stone. Diamond Engagement Rings
On either side of this are round brilliant cut diamonds, which taken together total 0.70 carats. They sit just below the princess cut stone, and they’re angled slightly out thanks to the curvature of the band. Their prongs come straight up from below, and thanks to their perfect positioning, this means these prongs are exactly parallel to those of the large diamond in the center.
White and Blue Diamond Accents
Small round diamonds are pave set across the top of both shank shoulders down to the mid-point on the band. These bring unparalleled glamour to the design, and they produce a wonderful sparkle that really helps the larger stones above to shine.
Round irradiated blue diamonds sit on both ring fronts directly below each of the stones in the center setting. These introduce an unexpected contrast to the piece, and their enchanting blue color is a wonderful complement to the brilliant white of the diamonds above. One of a Kind Engagement Rings
