Cocktail glass pendant necklace bearing 'SNW' tag (not authenticated)

This fashion jewelry necklace features a gold-tone metal chain and a prominent cocktail glass pendant. The chain is constructed with alternating elongated links and smaller round links, terminating in a lobster clasp and an adjustable extension chain. A small, rectangular metal tag near the clasp is visibly stamped with the letters "SNW". The pendant suspended from the center of the chain takes the form of a martini or cocktail glass. The bowl of the glass displays an iridescent or pearlescent finish with a textured, crystal-encrusted rim resembling salted glass. The stem is made of stacked clear faceted beads, and the base appears flat and dark in tone. A small, faceted green stone bead attached near the rim suggests a garnish such as an olive or lime. The overall condition appears clean, with bright metal finish and no visible damage or heavy wear, consistent with new or lightly handled costume jewelry. The style points toward modern novelty fashion accessories. The attribution rests upon the visible "SNW" stamp on the tag near the clasp. The owner provides additional context, user-attributed as "Supr Nova Wrists, new", which remains unverified by physical inspection or independent documentation.

Based on the provided image, I have evaluated this fashion jewelry necklace featuring a cocktail glass pendant and a tag bearing the letters 'SNW'. Per user submission, the owner identifies this piece as 'Supr Nova Wrists, new'. Based on what I can see in the photograph, the metal finish appears bright and clean, with no visible damage, and the crystal-encrusted rim and bead details are intact. However, I can't verify the materials or quality from a photo alone, and physical inspection would be needed to confirm the exact metal composition and stone settings. The basis for the value estimate assumes the user's attribution is correct, placing it in a modest novelty costume jewelry tier where comparable fashion pieces typically trade in the $35 to $60 range. General market demand for playful, novelty costume jewelry is driven largely by trend and aesthetic appeal rather than intrinsic material value. If physical inspection reveals the piece to be a replica, unbranded copy, or 'in the style of' rather than an official piece bearing the stated attribution, the value would drop significantly, likely to the $15–$25 range. To establish the actual attribution and value with certainty, what would be needed is in-person examination by a decorative arts or costume jewelry expert, hallmark verification, and provenance documentation, as an unauthenticated piece of this type would typically sell for less.
