Estate 18K Cushion Cut Emerald Marquise Diamond Large Cocktail Ring 11.77ct GIA

An extraordinary estate emerald and diamond ring crafted in luxurious 18 karat white gold, showcasing a commanding 11.77-carat natural cushion-cut emerald as its centerpiece. The emerald displays a glowing, saturated green with a gentle mint overtone that lifts the color beautifully, giving the stone that rare illuminated quality collectors look for. The crystal is lively and full of internal movement, creating flashes of brightness with even the slightest change of angle. It is accompanied by a GIA laboratory report noting F2 clarity enhancement. Although the report does not identify geographic origin, the gem’s hue, saturation, and internal character strongly align with Brazilian material.
Encircling the emerald is an elegant, crown-like halo of approximately 2.90 carats of marquise- and round-cut diamonds, arranged in alternating points that create a remarkable frame of fire around the center stone. Each diamond has been carefully matched in G–H color and VS1–VS2 clarity, contributing to a halo that is both bright and intricately detailed, enhancing the emerald without overpowering it.
The ring has substantial finger presence, measuring a full inch from top to bottom, yet maintains an airy balance thanks to the openwork beneath the setting. The overall effect is bold, glamorous, and unmistakably refined — the type of vintage estate jewel that stands confidently in any collection.
