Modern open-circle pendant on a snake-style chain

This piece appears to be a contemporary necklace featuring an open-circle (halo or eternity style) pendant suspended from a slender snake-style chain. The pendant is channel-set with a continuous row of rectangular stones, which are stylistically consistent with baguette-cut diamonds or cubic zirconia. These stones are aligned radially around the circumference of the silver-toned metal mounting. The metal itself exhibits a high-polish finish, which is consistent with sterling silver, white gold, or platinum, though no hallmark is visible in the provided image to verify the alloy. The construction of the pendant includes a slide-style attachment, where the chain passes directly through the body of the pendant rather than a traditional bail. The chain appears to be a fluid metal snake chain with a tight, rounded serpentine link pattern. The overall design is consistent with modern minimalist fine jewelry styles from the late 20th or early 21st century. Condition appears excellent with no visible tarnishing or lost stones in this view. Without physical inspection, the identity of the stones and the specific metal content cannot be determined; identification is based purely on visual stylistic attributes.

I have examined the image of this modern open-circle pendant suspended on a snake-style chain. Based on what I can see, the piece features a contemporary aesthetic with channel-set rectangular stones, which are stylistically consistent with baguette-cut diamonds or high-grade cubic zirconia. The high-polish metal finish suggests sterling silver or white gold, though I cannot verify the specific alloy or the identity of the stones from a photograph alone. Without visible hallmarks or a physical inspection to test for metal purity and stone refractive indices, any identification must be treated as a working hypothesis. The estimated value range of $150 to $450 is based on the assumption that the piece is composed of sterling silver and semi-precious stones or top-tier crystals, consistent with mid-market designer boutique jewelry. If physical testing were to reveal 14k white gold and natural diamonds, the value would significantly exceed this range, potentially reaching $1,200 to $2,500. Conversely, if the item is found to be a base-metal replica with synthetic stones, its market value would likely fall below $50. Market demand for minimalist geometric jewelry remains steady; however, the lack of a verified maker's mark limits the premium. To confirm a higher valuation, I would need an in-person examination to verify hallmarks, perform a diamond-point test, and inspect the link construction of the snake chain. Any final value is contingent upon these analytical results and the verification of the materials used in construction.
