pendant necklace with faceted gemstone

This piece consists of a delicate gold-toned chain holding a teardrop-shaped pendant featuring a prong-set, faceted blue or greyish gemstone. The pendant rests inside a hinged velvet-lined jewelry box that features a gold-stamped interior lid lining bearing text that appears to read "Rings 'N Things", which serves as unverified context. The owner supplies the context that this item is "14k rings and things", which is treated as an unverified user-supplied attribution. Because physical hallmarks such as karat stamps are not clearly legible from the photograph alone, the precise metal purity and gemstone composition cannot be established through visual inspection, and the identification remains hedged as a pendant necklace. The item exhibits clean lines, a polished finish on the pendant bezel, and typical wear consistent with vintage or modern costume or fine jewelry. Stylistic features suggest a mid-to-late 20th-century aesthetic, but physical testing in person is required to verify metal content and gemstone type.

Based on what I can see in the provided photograph, this item consists of a delicate gold-toned chain holding a teardrop-shaped pendant featuring a prong-set, faceted blue or greyish gemstone, housed in a hinged velvet-lined jewelry box that appears to bear the interior lid text 'Rings 'N Things'. Per user submission: attributed to 14k rings and things. I cannot verify from a photo alone whether the metal is solid 14-karat gold or the exact composition of the gemstone, as physical hallmarks such as karat stamps are not clearly legible and would need physical inspection to confirm. My appraisal value estimate of $150 to $300 assumes the owner's attribution is correct and that the metal tests as 14k gold with a genuine gemstone. General market demand for mid-to-late 20th-century vintage pendant necklaces of this style remains steady among collectors of costume and fine estate jewelry, though pieces lacking precious metal verification typically trade at lower price tiers. If physical testing reveals the item to be a reproduction, gold-plated replica, or unattributed costume piece in a similar style, the value would likely drop to the $30–$75 range. To confirm authenticity, metal purity, and gemstone type, an in-person examination by a qualified gemologist, hallmark verification, and scientific testing such as acid or XRF testing would be necessary.
