In this classically styled and regal jewel, a 2.74-carat oval sapphire with a deep lake-blue hue radiates from within a sparkling halo of bright white round brilliant-cut diamonds, and is supported by shoulders set with flashing tapered baguettes, while fine millegrain edges add textured detail. For the days, or nights, when you’re feeling princess-y. Total diamond weight, .75 carat. Crafted in gleaming platinum, it is currently ring size 5 3/4.
