GIA 3.51 carat old mine cut diamond platinum engagement ring

This exceptional engagement ring is a refined tribute to antique diamond romance, reimagined through modern craftsmanship. At its center is a magnificent 3.51-carat Old Mine cut diamond, certified by GIA and celebrated for its softly squared outline, broad facets, and unmistakable antique personality. The Old Mine cut offers a romantic, glowing brilliance—less sharp than modern cuts, yet deeply captivating—allowing light to pool and shimmer with warmth and depth. Its J color adds a gentle, vintage glow, beautifully balanced by the diamond’s exceptional VS1 clarity.

Surrounding the center stone is a graceful arrangement of twenty-two accent diamonds totaling approximately 0.70 carats, composed of single and baguette cuts. These diamonds introduce both sparkle and structure, blending delicate scintillation with clean, architectural lines. Their bright F–G color and refined clarity enhance the central diamond without overwhelming it, creating a harmonious frame that elevates the overall design.

Crafted entirely in platinum, the ring has a luxurious weight and a sleek, enduring presence. The cool-toned metal provides the perfect backdrop for the diamonds, emphasizing contrast, brilliance, and longevity. Though modern in its 2025 creation, the ring carries the soul of antique design, seamlessly bridging past and present.

Elegant, powerful, and timeless, this engagement ring is ideal for those who love the romance of historic diamond cuts but desire modern refinement and craftsmanship—an heirloom-quality piece designed to be cherished for generations.
