Gold-tone necklace with celestial and heart charms

This item is a yellow gold-toned necklace featuring an integrated pendant section of four charms arranged in a linear fashion. The charms appear to be two polished hearts on the outer edges, flanking a five-pointed star and a crescent moon. The chain is an oval-link or cable style, terminating in a spring ring clasp. A small rectangular metal tag near the clasp bears markings that are difficult to read definitively from the image, though one side appears to have a numerical stamp and the other side features a stylized cursive logo that is consistent with branding used by costume jewelry manufacturers like Monet or Napier. Without physical testing, it is impossible to determine its metal composition, though the lustrous surface is consistent with gold plating or gold-filled metal. The construction shows some slight surface scratches and minor dulling of the finish, which is typical for pre-owned jewelry. The design is stylistically consistent with late 20th-century fashion jewelry, possibly from the 1980s or 1990s. The attribution to a specific brand remains a hypothesis until the hallmark on the small metal tag can be viewed under magnification by an expert.

I have examined the image provided of the gold-tone celestial charm necklace. Based on what I can see, the item features a series of hearts, a star, and a crescent moon, which is a design motif highly characteristic of late 20th-century costume jewelry. The small rectangular tag bears a logo that appears consistent with marks used by manufacturers such as Monet or Napier, though I cannot verify this attribution from a photo alone. The valuation assumes the piece is a high-quality costume jewelry item from a recognized brand of that era. I can't determine the exact metal composition without physical testing; while it has the appearance of gold plating, a physical inspection is required to distinguish between gold-filled, plated, or base metal. The presence of surface scratches and minor dulling suggests a pre-owned condition, which is factored into this estimate. Generally, the market for vintage costume jewelry of this style remains stable, with demand driven by 'retro' fashion trends. To confirm the identity and value, an in-person examination under magnification is necessary to read the hallmarks. A physical test for metal purity and a verification of the manufacturer's mark would be required to move beyond the current working hypothesis. If the piece is found to be an unattributed 'in the style of' necklace without a designer mark, or if the metal finish is significantly degraded, the value would likely fall to the $5 - $15 range. Conversely, if the hallmarks are verified as a sought-after designer, the value would sit at the higher end of my estimate.
