Turquoise Square Cabochon Necklace and Earring Set

This is a costume jewelry set consisting of a necklace and a pair of matching clip-on earrings. The dominant feature of the set is the vibrant turquoise-colored square cabochons, likely made from resin, glass, or plastic, which are set into gold-toned metal findings. The necklace is a choker-style piece with a linked chain, featuring approximately ten square cabochons spaced evenly along the front half of the chain. Each cabochon is enclosed in an irregular, open-work gold-toned metal surround, which is then connected to the next by oval-shaped links. The chain itself appears to be a basic cable or curb link, with an extender chain and a small, round bead or charm at the end of the extender, suggesting adjustability for length. The clasp mechanism is not clearly visible but appears to be a lobster clasp or similar swivel-hook closure. The matching earrings are clip-on style, each featuring a single turquoise square cabochon set in a similar gold-toned, open-work irregular surround as seen on the necklace. The metal shows some signs of wear, particularly some dulling of the gold tone and potentially minor surface scratches consistent with use. No specific maker's marks or signatures are visible in the provided images. The overall design suggests a mid-20th century to contemporary costume jewelry aesthetic, possibly from the 1960s-1980s or a more modern reproduction inspired by these eras. The craftsmanship appears to be typical of mass-produced costume jewelry, focusing on visual appeal rather than fine material value.

I have visually examined this Turquoise Square Cabochon Necklace and Earring Set. Based on my assessment, this is a costume jewelry set featuring vibrant turquoise-colored square cabochons, likely made from resin, glass, or plastic, set into gold-toned metal findings. The condition shows signs of wear, including dulling of the gold tone and potential minor surface scratches, consistent with its likely age and material type. Authenticity as fine jewelry is not applicable, as its construction and materials are characteristic of mass-produced costume pieces. No maker's marks were visible in the image, which is common for this type of jewelry. Market conditions for vintage costume jewelry of this nature are generally moderate. While turquoise-colored items often have steady appeal, the use of non-precious metals and materials, along with typical mass-production craftsmanship, keeps values modest. Comparables in the online marketplace (e.g., Etsy, eBay for vintage costume jewelry with similar aesthetics from the 1960s-1980s) show similar sets retailing in the $20-$60 range, depending on condition and specific design appeal. Demand for such pieces exists among collectors of vintage costume jewelry and those seeking unique accessories, but it is not considered rare. The primary factor impacting value is the materials' nature and the wear observed. Without physical inspection, I cannot definitively confirm the cabochon material (resin vs. glass vs. plastic) or precisely assess the extent of metal wear or potential damage to the clip-on mechanisms. A direct examination would also be needed to check for any hidden manufacturer's marks or to confirm exact material composition (e.g., specific metal purity if it were plated jewelry with a premium base metal).
