Gold-tone double-strand chain necklace bearing a signature for Kramer

This item is a costume jewelry necklace featuring a double-strand design. The necklace is composed of elongated, oval-shaped links with a textured, brushed gold-tone finish. These links are interconnected by smaller, smooth circular rings, creating a layered, mid-century modern aesthetic. The clasp assembly includes two circular end pieces with a radiating ribbed texture, joined by a fold-over clasp. A macro image of the clasp reveals a stamped signature that reads "KRAMER©". The presence of the copyright symbol suggests a production date after 1955, making the design consistent with Mid-Century Modern American costume jewelry from the 1950s or 1960s. The metal exhibits visible signs of age-related wear, including significant green verdigris or oxidation on the textured end pieces and minor plating loss on the clasp mechanism. The owner identifies this as a 'vintage Kramer of New York' piece purchased by a grandparent in the mid-20th century; while the visible mark and construction are stylistically consistent with works by Kramer of New York, these markings remain unverified as authentic without physical inspection by a jewelry specialist to rule out period-correct replicas or later modifications.

Based on the provided images, I observe a double-strand, gold-tone costume jewelry necklace featuring elongated, textured links. Per the user submission, this item is attributed to Kramer of New York and was purportedly purchased in the 1950s or 1960s. The clasp bears a mark reading 'KRAMER©', which is stylistically consistent with post-1955 production by the company. However, I must treat this attribution as a hypothesis; I cannot verify the maker from photographs alone, and an in-person examination by a costume jewelry specialist would be necessary to rule out period-correct replicas or later modifications. Condition plays a paramount role in the valuation of mid-century costume jewelry. The images reveal significant age-related wear, notably heavy green verdigris (oxidation) on the textured end pieces and minor plating loss on the clasp assembly. While Kramer pieces are generally collectible, this level of degradation severely limits its current market appeal. The estimated value reflects what this item might bring assuming the attribution is accurate but accounting for the poor condition. Comparable Kramer pieces in pristine state often sell for notably more, but the required restoration or potential permanent metal damage limits this piece's value. If this item is unattributed or a reproduction, its value would be purely nominal, likely under $10.
