Mid Century GIA 3.45 carat Colombian emerald diamond platinum ring

A rectangular emerald cut emerald glows with a rich, grassy green at the center of this ring, its step-cut facets laying out mirrored panels of color like the deck of a ship. The 3.45 carat stone is of Colombian origin, the source most prized for exactly this saturated, velvety hue, and it is documented by GIA report number 2241053625 with a treatment grade of F2. Beside it, four baguette and carré cut diamonds, weighing approximately 0.60 carat in I-J color and VS-SI clarity, step down the shoulder in a clean, geometric staircase that echoes the emerald's own cut. Crafted in platinum and hallmarked with a purity mark and a maker's mark, the ring weighs 5.15 grams, a solid, balanced weight on the hand. Circa 1950, it suits someone who loves the crisp architecture of Mid Century design and wants a Colombian emerald with a certificate behind it, worn as a statement engagement ring or a very special everyday piece.
