Solitaire Diamond or CZ Pendant Necklace

This item is a solitaire pendant necklace featuring a single, round brilliant-cut stone set in what appears to be a four-prong basket setting. The stone, which could be a diamond or a cubic zirconia, exhibits strong brilliance and scintillation, characteristic of a well-cut faceted gem. It measures approximately 4-5 mm in diameter based on visual estimation, suggesting a weight of roughly 0.25 to 0.50 carats if it were a diamond. The metal of the setting and the accompanying chain appears to be silver-toned, possibly white gold, sterling silver, or platinum, given its bright, reflective surface. The chain is an open-link style, likely a cable chain, with small, oval-shaped links. The overall construction appears delicate yet sturdy for daily wear. There are no readily visible manufacturer's marks or signatures from the provided images, so the maker and precise metal content cannot be definitively determined. The condition seems excellent, with no apparent wear, scratches, or damage to the stone or the metal components. The design is classic and timeless, indicative of a contemporary or modern style, likely produced in the last few decades. The craftsmanship appears to be of good quality, focusing on showcasing the central stone effectively.
