Emerald-Cut Diamond or Moissanite Halo Engagement Ring with Multi-Band Stack

This jewelry piece consists of a prominent emerald-cut center stone set within a classic rectangular pavé halo. The center stone exhibits high clarity and a distinct step-cut pattern characteristic of the emerald cut, likely weighing between 2.0 to 3.5 carats. The halo and the main band appear to be crafted from a white metal, such as 14k or 18k white gold or platinum, given the cool silvery luster. The ring is styled with a stacked aesthetic, featuring at least two additional flanking bands: one appears to be a plain high-polish metal band, and the other features a detailed twisted or 'rope' texture design. This combination suggests a contemporary bridal set or a curated fashion stack. The prongs are discreetly positioned at the corners to secure the main stone without obscuring the step-cut facets. No visible hallmark is identifiable from the image, but the craftsmanship indicates a modern production, likely from the late 20th or early 21st century. The condition appears well-maintained with high brilliance in the stones, though the metal components likely show minor surface abrasions (microwear) consistent with regular use. The overall design emphasizes a balance between vintage geometric cuts and modern textural band layering.
