Costume jewelry necklace, bearing a tag reading 'Mariana' (not authenticated)

This is a decorative costume jewelry necklace composed of linked circular and floral-shaped metal components embellished with small faceted clear crystals and pearl-like cabochons. The metal appears to have a dark, antiqued silver-tone finish. The necklace features alternating patterned links including floral motifs, spirals, and textured circular settings filled with pavé-style stones. A lobster clasp secures the chain, and a small metal tag hangs near the clasp bearing text that appears to read 'Mariana'. The owner supplies unverified context that this piece is by the designer Mariana. The piece exhibits standard construction methods consistent with mid-to-late twentieth or twenty-first-century fashion jewelry, featuring soldered jump rings and prong-set synthetic stones. The overall physical condition appears good based on the photograph, with no glaring missing stones or major structural damage immediately visible, though minor surface wear and patina are present on the metal components. The attribution in the name rests directly on the legible text stamped on the hanging tag, but the piece remains unauthenticated as to its exact workshop origin or age.

Based on what I can see from the provided photograph, this is a decorative costume jewelry necklace featuring linked circular and floral motifs set with faux pearls and clear faceted crystals in an antiqued silver-tone finish. The owner identifies this as a piece by the designer Mariana, and I can observe a small hanging tag bearing text consistent with that maker. However, I cannot verify from a photo alone whether this is an authentic workshop piece or a later imitation. Physical inspection by a specialist would be needed to inspect metal composition, stone quality, and exact stamp impressions to substantiate the attribution. My appraisal estimate of $65 to $125 reflects the typical secondary market value for a Mariana fashion necklace in good pre-owned condition, assuming the owner's attribution is correct. Designer costume jewelry of this style generally sees steady decorative demand, though condition issues such as foil backing decay or loose stones can quickly impact desirability. If physical examination were to demonstrate that this is an unbranded reproduction or an unsigned copy in the style of Mariana, the decorative secondary market value would typically fall to around $15 to $30.
