Gold Pink Gemstone Ring and Gold Braided Band with Stones

This image features a collection of jewelry pieces, primarily focused on two distinct rings. The most prominent is a yellow gold ring featuring a large, rectangular emerald-cut pink gemstone, likely a laboratory-grown ruby or pink sapphire, held in a bar setting. The stone exhibits a vibrant magenta-pink hue with visible internal facets. The band of this ring has a textured, ribbed, or 'shrimp' style shoulder detail. The second ring is a yellow gold band with a twisted or braided rope-style border. It is set with a channel of small, dark round-cut stones, which appear to be either sapphires or dark spinel. The gold across these pieces shows signs of light wear and surface scratches consistent with age and use. There are visible hallmarks or stamps on the interior of the bands, though they are too blurred to read clearly, suggesting a manufacturing standard of 10k or 14k gold. The style is indicative of late 20th-century jewelry design, possibly the 1980s or 1990s. The overall craftsmanship shows mass-market commercial quality with standard prong and channel setting techniques. Surface patina reflects a vintage condition without catastrophic damage to the stone facets.
