Vintage 'Howard' Stamped Jewelry Clasp with Chain Sections

The item in question appears to be a vintage or antique jewelry clasp, specifically a spring ring or similar closure mechanism, attached to a chain. The clasp itself is oval-shaped, made of a warm-toned yellow metal, likely gold, gold-filled, or gold-plated, given its aged appearance and the 'Howard' marking. The surface of the clasp exhibits a slight patina consistent with age, suggesting it is not newly manufactured. The visible marking 'Howard' is etched or stamped into the metal of the clasp's inner mechanism. This could indicate the manufacturer of the clasp component or the entire piece of jewelry. The chain attached to the clasp consists of two distinct styles: one section features a classic oval link chain, while the other is comprised of delicate, heart-shaped or figure-eight links, suggesting an decorative or elegant design for the full piece of jewelry. Both chain sections are also in a matching yellow metal. The overall quality of construction appears to be good, with no obvious signs of severe damage or repair. The spring mechanism of the clasp seems to be intact, though its functionality cannot be fully assessed from the image alone. The presence of the 'Howard' mark is a key feature for identifying the maker and potentially dating the piece. Based on the style of the chain and clasp, it is likely from the early to mid-20th century, possibly Art Deco or Retro period, though more information about the full piece of jewelry would be needed for a precise dating.
