Black Pearl Necklace and Earring Set (not authenticated)

This jewelry set consists of a strand of dark-toned spherical pearls paired with matching stud earrings, presented together in a red hinged presentation box lined with white or cream-colored satin and velvet. The pearls display a deep iridescent dark coloration, exhibiting lustrous overtones with hints of green, purple, and blue hues under the light. The necklace is strung as a continuous single strand, featuring uniformly graduated or near-uniform round beads that appear to have a smooth surface texture and a reflective nacre coating. The matching stud earrings feature single round pearls mounted on posts. The clasp visible on the necklace is a small, decorative metal fixture, possibly white gold or platinum-toned metal, though metal purity stamps are not clearly legible from this vantage point. The overall presentation is consistent with mid-to-late 20th-century fine jewelry styling, but the specific origin, treatment history (such as whether the pearls are naturally dark, dyed, or cultured), and materials remain unverified. There are no visible maker's marks or brand stamps discernable in the photograph, and the attribution is based entirely on the visual presence of a pearl necklace and earring set in a fitted display case.

Based on what I can see in the photograph, this jewelry set consists of a strand of dark-toned spherical pearls with matching stud earrings, presented in a red hinged box. The pearls display lustrous overtones with hints of green, purple, and blue. However, I can't verify from a photo whether the pearls are naturally dark, dyed, or cultured, nor can I read any metal purity stamps on the clasp. Physical inspection would be needed to confirm the nature of the nacre, the metal content of the clasp, and whether the pearls are saltwater or freshwater. My value estimate of $400 to $800 assumes the piece is comprised of cultured pearls with precious metal findings in good condition. General market demand for classic pearl sets remains steady for decorative mid-to-late 20th-century jewelry, though unbranded and unauthenticated sets generally trade at modest price points. To establish full attribution and value, an in-person examination, hallmark verification, and expert appraisal would be necessary. If physical testing reveals the pieces are modern costume reproductions using glass or plastic imitation pearls rather than nacre-coated pearls, the market value would drop significantly to the $30 - $75 range.
