Line-style necklace with light-colored stones

This item is a link-style line necklace, often referred to as a tennis-style necklace, featuring a continuous row of pale, possibly lilac or light blue oval-cut stones. Based on the visual evidence, the metal setting appears to have a silver-toned finish consistent with sterling silver, white gold, or a plated base metal. The stones are held in individual prong settings, alternating with 'X' shaped decorative metal spacers, a design often associated with late 20th-century or contemporary fashion jewelry. The stones have a subtle pleochroism or color-shifting quality in this lighting, which could be consistent with tanzanite or treated quartz, though synthetic alternatives like cubic zirconia cannot be ruled out without physical testing. No maker's marks or metal purity hallmarks (such as '925' or '14K') are clearly legible in the provided photograph, making any specific material or brand attribution a hypothesis only. The construction appears to be machine-made with articulated joints for flexibility. The overall condition looks good with no missing stones visible, though there is minor surface wear consistent with light use. Due to the lack of visible hallmarks, this identification remains unverified and subject to in-person inspection by a specialist.

I have examined the image of this link-style line necklace. Based on what I can see, the piece features light lilac or blue-toned oval stones set in a silver-toned metal with 'X' decorative spacers. I cannot verify the metal purity or stone identity from a photo alone; however, the design is consistent with jewelry utilizing sterling silver and possibly low-grade tanzanite or treated quartz. I treated the possibility of these materials as a working hypothesis for this estimate. This value range reflects the general market demand for contemporary sterling silver gemstone necklaces. I cannot determine if the stones are natural, synthetic, or glass without physical testing, such as a refractometer or thermal conductivity test. Furthermore, I cannot see any legible hallmarks like '925', so I am assuming the metal is silver-toned rather than solid white gold. The basis for this estimate assumes the materials are as suggested; if physical inspection reveals the item is a base-metal fashion piece with cubic zirconia, the value would likely fall below $50. Conversely, if the stones are high-quality natural gems in white gold, the value would increase significantly. To reach a more stable conclusion, an in-person examination by a specialist is required to test stone hardness, check for metal hallmarks, and assess the articulation and clasp under magnification. For now, this estimate serves as a baseline for an item of this style and apparent condition.
