Dragonfly pendant in the style of Tiffany & Co.

A white metal pendant or slide charm designed in the form of a stylized dragonfly, featuring an openwork wing design and a vertical body set with small, round colorless stones. The front displays a polished finish with stones graduated in size along the tail. The reverse reveals several marks, including an incised '14KTHL' on the left wing, which appears consistent with markings for 14-karat gold from the 'Tiffany Heritage Line' or related collections. The right wing bears a copyright symbol and an 'A' mark. This piece is stylistically consistent with the 'Dragonfly' collection by Tiffany & Co., though this attribution is a hypothesis subject to physical testing of the metal and stone quality. The presence of a safety chain suggests it may have originally been part of a bracelet or brooch assembly. Visible condition includes surface scratches and minor tarnish consistent with use and age. The stones are prong-set, and the casting shows smooth interior work. The owner has provided images showing both the face and the hallmarked underside for identification. Please note that hallmarks can be replicated, and this item remains unauthenticated without in-person professional inspection.

Based on the images provided, I have examined this white metal dragonfly pendant which the owner identifies as a Tiffany & Co. piece. From what I can see, the item reflects the 'Dragonfly' design motif often associated with that brand, featuring an openwork wing structure and a stone-set body. The reverse bears marks consistent with '14KTHL' and a copyright symbol. However, I cannot verify the metal's purity or the diamond quality from a photo; a physical inspection using acid testing or XRF analysis and a jeweler’s loupe is necessary to confirm the materials. My value estimate of $450 to $850 is based on the working hypothesis that the piece is composed of 14-karat gold and genuine diamonds as suggested by the markings. This range reflects typical market behavior for pre-owned luxury designer charms of this scale. If the attribution as a 'Tiffany Heritage Line' piece were to be formally supported by in-person professional inspection and authentication, the value could potentially trend toward the higher end of the secondary market. Conversely, if the item is found to be a reproduction, an 'in the style of' piece, or made of base metal/simulants, the value would likely drop significantly to a decorative range of $25 to $75. To reach a more precise valuation, one would need to document the weight, confirm the hallmark's legitimacy against known manufacturer records, and have the stones graded by a gemologist. The presence of a safety chain suggests a modification from an original brooch or bracelet, which may impact collectibility compared to a pristine original pendant configuration.
