A pair of vintage-style clip-on earrings featuring a decorative interwoven knot or 'love knot' design. The construction utilizes a mixed-metal aesthetic, with multiple concentric loops in polished silver-tone metal accented by a central strand in a gold-tone finish. These earrings measures approximately 0.75 inches in width. The fastening mechanism is a classic screw-back or paddle-clip hybrid commonly found in mid-to-late 20th-century costume jewelry, designed for non-pierced ears. The metal appears to be base metal with high-quality plating, showing a bright, reflective surface with minimal tarnishing or surface oxidation. There are no immediate maker's marks visible in the orientation provided, though such pieces are characteristic of brands like Monet, Trifari, or Napier from the 1970s-1980s era. The condition is excellent with no visible loss of plating or mechanical failure in the clips. The interlocking ribbons are smoothly finished with rounded edges, indicating good quality control and decorative craftsmanship intended for everyday formal or business attire.

I have conducted a visual examination of the Two-Tone Interwoven Knot Clip-On Earrings. The items present in excellent vintage condition, exhibiting high-quality gold and silver-tone plating with no evidence of 'pitting,' wear-through, or oxidation. The mechanical integrity of the paddle-clip/screw-back hybrid remains intact, suggesting these were well-maintained or rarely worn. While similar in construction to the signature work of Monet or Napier, the absence of a visible hallmark classifies these as unbranded high-end costume jewelry of the 1970s–1980s. The current market for vintage costume jewelry favors 'career-wear' staples; however, value is primarily driven by brand recognition and metal purity. As these are base-metal clips, they lack the intrinsic value of precious metals. Comparables for unsigned pieces of this era typically sell within the $35–$70 range. The timeless knot motif maintains steady demand among collectors of classic accessories, though they are not considered rare. Values are significantly impacted by the lack of a designer signature, which would otherwise add a 30-50% premium. My assessment is limited by the digital format; I cannot verify the base metal composition or detect microscopic stress fractures in the hinges without a physical loupe inspection. For definitive authentication and valuation, an in-person examination is required to check for hidden marks on the interior clip pads. No scientific testing (such as acid testing) is recommended as these are clearly plated, and such tests could damage the aesthetic finish.
