Gold-tone chain necklace with circular stone-set pendant

This piece appears to be a fine gold-tone chain necklace featuring an open circular pendant set with numerous clear, round brilliant-cut stones, which are consistent with simulated diamonds, cubic zirconia, or crystal accents. The pendant design consists of an intertwined or braided circular lattice pattern, connected to the chain by a polished gold-tone bail. The item features a delicate cable-style chain construction. In terms of condition, there appears to be slight discoloration or tarnishing along sections of the metal chain, along with light surface wear, which is common in plated or costume jewelry. No hallmarks, maker's marks, or metal purity stamps are clearly legible from the provided photo; physical inspection would be required to verify any metal composition or stone types. The owner attributes this item to Stauer, though this brand claim remains unverified as no branding is visibly discernible in the image. The style is consistent with late 20th to early 21st-century contemporary costume jewelry.

Based on what I can see in the provided image, this item is a contemporary fine gold-tone chain necklace with an open circular stone-set pendant featuring an intertwined lattice pattern. The pendant is set with numerous small, clear, round brilliant-cut stones consistent in appearance with cubic zirconia, crystal, or glass accents. I can't verify metal purity or stone composition from a photo alone; an in-person physical inspection, including chemical or XRF metal testing and gemological testing, would be required to confirm the materials. Slight discoloration and surface wear are visible along sections of the cable-style chain, which is typical for gold-plated or base-metal costume jewelry. Per user submission, this item is attributed to the brand Stauer. However, no maker's marks or hallmarks are clearly legible in the photo, so this brand attribution remains an unverified hypothesis. The estimate provided reflects the general secondary market value for contemporary, plated costume jewelry of similar design and condition, assuming base metal construction with synthetic stones. Fashion and costume jewelry of this style sees modest demand on the resale market, typically selling through online vintage or estate outlets. If an in-person examination were to confirm that the metal is solid karat gold and the stones are natural diamonds, the valuation would increase significantly. Conversely, if the piece is an unattributed fashion item with plating wear, it remains within the lower end of the $15 to $30 range. To establish a firm identification and value, hallmark verification, provenance documentation, and scientific testing of the metal and stones by a qualified jeweler would be necessary.
