GIA 3.29 carat old mine cut diamond platinum engagement ring

This exceptional engagement ring captures the romance of antique diamond cutting while embracing the refinement of modern design. At its center is a magnificent 3.29-carat Old Mine cut diamond, certified by GIA and prized for its softly squared shape, broad facets, and glowing, antique-style brilliance. Unlike contemporary cuts, the Old Mine cut offers a warmer, more soulful sparkle, allowing light to gather and shimmer with depth and character. Its J color enhances this romantic glow, while the impressive VS2 clarity ensures a beautifully clean and luminous appearance.

Surrounding the center stone is a meticulously arranged halo of twenty-three accent diamonds totaling approximately 0.90 carats. A combination of single and baguette cuts introduces both delicate sparkle and crisp architectural lines, framing the center diamond with balance and sophistication. The bright F–G color and refined clarity of the accent diamonds elevate the overall composition, adding dimension without distracting from the commanding centerpiece.

Crafted entirely in platinum, the ring offers strength, longevity, and a sleek, luminous backdrop that enhances the diamonds’ brilliance. Though created in 2025, the design feels timeless—bridging historic inspiration with contemporary craftsmanship. Its elegant proportions and thoughtful detailing make it both visually striking and effortlessly wearable.

Refined, romantic, and undeniably powerful, this ring is ideal for those who cherish the character of antique diamonds while seeking the precision and confidence of modern fine jewelry—a true heirloom for the next generation.
