About the Item

This elegant platinum ring showcases a mesmerizing 2.20 carat cushion-cut blue sapphire, certified by GIA as natural corundum, transparent, and heated only to enhance its vivid color. The sapphire displays a captivating rich royal blue hue and is beautifully complemented by a pair of half-moon cut diamonds set on either side, adding brilliance and balance to the design. The sapphire’s refined proportions and exquisite step-brilliant cut crown lend the piece a timeless character, while the sleek platinum setting enhances its contemporary appeal. The side diamonds are expertly set with minimal double prongs at the band, offering a clean and architectural profile that allows the center stone to take the spotlight. A superb choice for a collector or as a unique engagement ring, this piece embodies Antinori’s distinctive blend of craftsmanship and classic sophistication.
