Gold Box Chain with Spring Ring Clasp

The item depicted is a segment of a gold chain, specifically showing the clasp mechanism and the end of the chain itself. The chain appears to be a 'box chain' or 'Venetian chain' style, characterized by its square, interlocking links that create a smooth, continuous surface. The links are of a consistent, fine gauge, suggesting a delicate yet durable construction. The material is clearly gold, exhibiting a rich, warm yellow hue typical of high-karat gold compositions. Attached to the chain is a spring ring clasp, a common and functional type of closure for necklaces and bracelets. The clasp consists of a circular hollow hoop with a spring-loaded mechanism that creates an opening for attachment. A small, rounded lever or 'thumbpiece' is visible, which, when pulled back, opens the ring. The visible portion of the chain connects to a small, teardrop-shaped bail or end-tag, which in turn is affixed to the spring ring clasp. This end-tag is where the hallmarks are located. Notable markings include '750' etched or stamped onto the end-tag, which signifies 18 karat gold (750 parts per 1000 pure gold). Below the '750' mark, there are additional faint markings that appear to be a 'star' symbol followed by numbers or letters (possibly '24 AU' or similar), indicating a maker's mark and potentially a country of origin or a registered workshop number. The 'star' symbol often denotes Italian assay marks. The overall condition appears excellent with minimal signs of wear. There is no visible damage, significant scratches, or repairs. The gold exhibits a natural, subtle patina consistent with age and occasional handling, enhancing its rich appearance. The craftsmanship appears to be of high quality, with smoothly finished surfaces and precise construction of the chain links and clasp. Based on the '750' mark and the style of the chain and clasp, this piece is likely of modern or late 20th-century manufacture, possibly Italian.
