About the Item

This authentic mid-century engagement ring centers on a 1.15 carat old mine cut diamond certified by GIA under report number 6535679451. The diamond carries a G color grade, offering a bright near-colorless appearance that pairs beautifully with its antique facet structure, while the SI2 clarity reflects natural inclusions consistent with vintage cutting styles that remain largely unnoticeable to the eye. The old mine cut delivers a soft, romantic brilliance with a deeper, more organic sparkle than modern round brilliant cuts. Flanking the center stone are 2 tapered baguette diamonds totaling approximately 0.30 carat, graded G-H color and VS clarity, adding clean architectural lines and a refined Art Deco-to-mid-century transition aesthetic that frames the center stone elegantly. The ring is crafted in platinum, prized for its strength, density, and naturally white sheen that enhances diamond brilliance while offering lasting durability. Originating from the 1950s mid-century era, the design reflects a shift toward cleaner geometry and streamlined elegance. It bears both a maker’s mark and a purity hallmark, confirming authenticity and craftsmanship. Weighing 3.84 grams, it has a light yet substantial feel on the hand. The ring is currently a size 4.5 and can be resized for a proper fit.
