Solitaire Pendant Necklace with Round-Cut Stone

The item is a solitaire pendant necklace, featuring a single, prominent round-cut stone set in what appears to be a four-prong or six-prong basket setting, likely crafted from a silver-toned metal such as sterling silver, white gold, or platinum, given its bright, reflective luster. The stone itself exhibits significant brilliance and fire, characteristic of a well-cut diamond or a high-quality diamond simulant like moissanite or cubic zirconia. Its size appears substantial, suggesting a carat weight of at least 1-2 carats if it's a diamond. The pendant is suspended from a thin, delicate chain, possibly a curb or cable link style, also in a matching silver-toned metal. The chain shows no visible signs of kinking or damage, and the overall condition of the necklace appears to be very good, with no obvious wear, tarnishing, or missing prongs. There are no discernible maker's marks or distinguishing engravings from the image provided. The style is classic and timeless, suggesting it could be of modern production, likely within the last 20-30 years, designed to be an everyday wearable piece or for special occasions. The craftsmanship seems neat and secure, with the stone well-centered and held firmly in its setting, indicating a reasonable level of quality.
