Screw-Back Earring Mechanism with Star Motif

The item appears to be the screw-back mechanism from an earring, held between two fingers with bright pink painted nails. The primary visible component is a yellow-toned metal, likely gold or gold-plated, forming a round, flat disc at the end of the screw mechanism. This disc features a distinct impressed or engraved mark: a six-pointed star, commonly known as the Star of David, with a small circular dot or indentation in its very center. The screw post is visible extending from this disc, further suggesting it's part of an earring back. Behind this disc and extending into the hand, a portion of what appears to be the ornamental front part of the earring is visible, showcasing a dark, textured or multifaceted surface, possibly black onyx, jet, or a dark enamel, with a decorative edge that appears to be silver-toned or white gold, possibly with small, clustered decorative elements. The overall construction suggests a vintage piece, as screw-back earrings were more common prior to the widespread adoption of clip-on or pierced earring styles. The metal shows a slight patina consistent with age, but no significant damage or wear is immediately apparent on the visible screw mechanism. The craftsmanship appears solid, with the star motif being a notable and potentially identifying characteristic, which could indicate the maker or the origin of the piece. The small size makes it difficult to assess further manufacturing details without additional magnification.
