Pendant necklace featuring a light violet-blue gemstone in the style of tanzanite or sapphire

This piece consists of a delicate, silver-tone fine metal chain attached to a small pendant. The pendant features an oval-cut gemstone with a light violet-blue hue, visually consistent with tanzanite, light sapphire, or blue topaz. The stone is set within a four-prong or cluster-style setting, crowned with small accent stones that resemble pave-set diamonds or synthetic stones (such as cubic zirconia or crystals). The metal appears to be a silver-toned alloy, potentially white gold, sterling silver, or platinum, though no hallmark or metal fineness stamp is legibly visible in the photograph. The overall design displays a contemporary or late 20th-century aesthetic. Hedged terminology is used for the metal composition, gemstone type, and maker as no stamps or signatures can be clearly read in the provided photo, requiring physical testing by a jeweler for precise composition and authenticity verification.

Based on my visual examination of the provided photograph, I have evaluated this light violet-blue pendant necklace. The piece features an oval-cut gemstone with a hue reminiscent of tanzanite, light sapphire, or blue topaz, accented by small white stones in a silver-toned metal setting. From a photo alone, I cannot confirm the exact gemological identity of the center stone, the accent stones, or the precise metal composition. No hallmarks or fineness stamps are clearly legible, meaning the metal could range from sterling silver to white gold or platinum, or potentially a non-precious alloy. Physical testing—such as gemological refractometer testing, diamond testing, and XRF metal analysis—would be required by a jeweler to confirm whether the materials are natural gemstones, synthetic lab-grown alternatives, or costume materials. Assuming the piece is crafted from sterling silver or low-karat white gold featuring a natural tanzanite or light sapphire with cubic zirconia or small diamond accents, the secondary market value is estimated between $150 and $450. Fine jewelry pieces in this delicate, contemporary style enjoy steady market demand due to their versatile aesthetic. This valuation is entirely contingent on material confirmation. If physical inspection reveals the metal to be a base alloy or the stones to be glass or synthetic cubic zirconia, the fair market value would decrease significantly to approximately $20 to $50 as fashion or costume jewelry. Conversely, if the piece is authenticated as high-karat gold or platinum with a high-grade natural gemstone, the valuation would shift higher depending on the weight and stone clarity.
