Gold-tone filigree brooch with faux turquoise cabochon

This piece is a vintage costume jewelry brooch featuring an intricate, openwork gold-tone metal frame adorned with a botanical motif of leaves and small berries encircling a central oval stone. The central element is a large cabochon with a polished dome, displaying a marbled, mottled teal and turquoise coloration that suggests a simulated turquoise, glass, or plastic material rather than genuine natural turquoise. The gold-toned metal mounting exhibits a warm finish with slight variations in patina, consistent with mid-20th-century costume jewelry construction techniques such as stamping and casting. The reverse side is not fully visible in the photograph, but standard pin-stem and catch mechanisms typical of the era are expected. There are no clearly legible maker's marks, signatures, or hallmarks visible on the front surface of the item. The aesthetic displays characteristics consistent with mid-century costume jewelry design, often associated with various commercial fashion houses of the 1950s or 1960s. The owner provided the unverified context 'Goldwater', which is noted here for provenance tracking but remains entirely unverified by visual inspection or maker's marks. The identification rests purely on the visible physical characteristics of the metalwork and stone without any supporting hallmark evidence.

Based on what I can see in the photograph, this piece is a vintage costume jewelry brooch featuring an openwork gold-tone metal frame with botanical motifs surrounding a simulated turquoise cabochon. I can't verify from a photo the exact metal composition, the materials of the central stone, or the presence of any maker's marks on the reverse side. Per user submission: the owner identifies this as associated with 'Goldwater'. This remains an unverified hypothesis, as no visible hallmarks are apparent on the front surface. My value estimate of $45-85 assumes the attribution is correct and that the piece dates to the mid-20th century in typical vintage condition with minor surface wear. Mid-century costume jewelry of this style generally appeals to collectors of vintage fashion accessories, though values fluctuate based on current design trends and maker popularity. If physical inspection reveals that the item lacks the proposed attribution or turns out to be a later reproduction, replica, or unattributed piece in the style of the era, the market value would likely decrease to the $15-30 range. To establish a more precise evaluation and assess authenticity, I would need physical inspection, hallmark verification, and expert appraisal to examine the construction techniques and any hidden signatures.
