Sterling silver lever-back earrings with lab-created or natural opal-style cabochons

A pair of circular, lever-back drop earrings featuring round, domed cabochons displaying iridescent play-of-color consistent with opal or lab-created opal. The stones show flashes of green, blue, and red against a translucent white body. Each stone is set into an 'nested' or 'infinity' style frame composed of three interlocking silver hoops, one of which appears to have a twisted rope texture. The earrings are constructed from what appears to be silver with a slightly darkened patina in the recessed areas. The reverse of one earring bears a prominently raised rectangular cartouche with stamped text reading 'ISRAEL', '925', and 'PZ'. The lever-back ear wires also show a small '925' stamp. While the markings suggest an Israeli origin and sterling silver purity, these cannot be treated as fact without metallurgical testing and provenance research. The design is stylistically consistent with late 20th-century or contemporary artisan jewelry from Israel. Visible condition shows light surface scratches and tarnish consistent with occasional wear.

Based on my visual examination of the provided images, these earrings appear to be artisan-style sterling silver drop earrings featuring opal-like cabochons. The markings on the reverse, including the '925' and 'ISRAEL', alongside the 'PZ' maker's mark, are consistent with jewelry produced by Paz Creations or similar Israeli artisan studios. However, I cannot verify the metallic purity or the natural origin of the stones from a photograph alone; physical metallurgical testing and a gemological inspection would be required to determine if the settings are solid sterling silver and if the stones are natural or lab-created opals. I am treating the Israeli attribution as a hypothesis rather than a fact, as marks can be reproduced. The value estimate is based on the assumption that the marks are accurate and the stones are high-quality lab-created or natural triplet opals. In the current secondary market, there is a steady demand for Israeli artisan silver, particularly pieces with 'boho-chic' or 'infinity' designs. If the items were found to be silver-plated base metal rather than sterling silver, or if the stones were identified as simple synthetic resin, the value would likely drop to $10–$20. The current condition shows minor tarnish and surface wear aligned with light use, which is typical for this market bracket. To confirm the origin and material, I would recommend an in-person hallmark verification and a thermal conductivity test for the stones. The provided range reflects the typical retail and auction performance for identified Israeli silver jewelry in similar condition.
