Heart-shaped pendant necklace in the style of Elsa Peretti for Tiffany & Co.

This item is a necklace consisting of a delicate silver-toned chain and an open heart pendant. The pendant appears to be a stylized, slightly asymmetrical 'open heart' design, which is stylistically consistent with the 'Open Heart' collection by Elsa Peretti for Tiffany & Co. The heart is pave-set or channel-set with numerous small, colorless round stones that resemble diamonds or white sapphires. The metal has a bright, polished finish consistent with sterling silver or white gold, though no hallmarks or metal purity stamps are legible in the provided image. The pendant is suspended on a fine link chain of a matching silver-toned metal. The piece is presented in a black velvet-style jewelry box with a cream-colored lining, which lacks visible branding. There are no visible condition issues such as missing stones or tarnishing in the photo, suggesting it has been well-maintained. The identification is hedged because no maker's marks, signatures, or karat stamps are visible for verification; final attribution would require an in-person inspection of the clasp and pendant reverse for official hallmarks.

Based on the image provided, I have examined this heart-shaped pendant necklace, which features a design stylistically consistent with the 'Open Heart' collection by Elsa Peretti for Tiffany & Co. The pendant is set with numerous colorless round stones and suspended on a fine link chain. While the polished finish is characteristic of sterling silver or white gold, I cannot verify the metal purity or the nature of the gemstones (e.g., diamonds vs. sapphires) from a photograph alone. The valuation of $250–$450 assumes the item is crafted of sterling silver and set with small diamonds, bearing markings consistent with the purported designer. This estimate reflects the high market demand for iconic designer-style jewelry in well-maintained condition. However, I must emphasize that this attribution is a hypothesis. I cannot see any hallmarks, signatures, or karat stamps, and the provided packaging lacks branding. A physical inspection is required to check the clasp and reverse for official marks to confirm the maker. Scientific testing would also be necessary to identify the stones. If this piece is found to be a reproduction, a non-designer copy, or 'in the style of' without the associated branding, the market value would likely decrease significantly, typically falling into the $25–$75 range for costume or unbranded silver-toned jewelry. The final value is contingent upon physical verification of materials and designer marks.
