Emerald-Cut Diamond Three-Stone Engagement Ring in White Gold

This is an elegant three-stone diamond engagement ring crafted in what is identified as white gold. The center stone is a prominent emerald-cut diamond, characterized by its rectangular shape and step-cut facets that create a 'hall-of-mirrors' effect. The center diamond is securely held by four corner prongs. It is flanked on either side by a single tapered baguette-cut diamond, oriented horizontally and set into the shoulders of the shank. The overall design aesthetics suggest a classic Mid-Century or Art Deco-inspired style, likely dating from the mid-20th century to modern day given its timeless appeal. The white gold mounting has a high-polish finish. While specific grades for clarity and color cannot be determined from the photo, the center stone appears to have high transparency. Notable condition observations include minor surface wear and light scratches on the metal band consistent with regular use, though no major structural damage or missing stones are visible. The prongs appear intact, though a professional cleaning and inspection of the setting's security would be standard for appraisal. There are no visible maker's marks or hallmarks shown in this view, though they would likely be found on the interior of the shank.
