Craftsmanship Details
Machine-tapered pin stem for sharpness; likely a cast or stamped bezel head; hand-polished finishes on the onyx and gold surfaces.

Origin & Maker
Likely North American or European manufacture; common in boutique jewelry catalogs of the mid-20th century. No distinct brand logo visible.
Era & Period
Late Mid-Century Modern to Retro; the organic, asymmetrical 'pebble' shape of the stone suggests 1960s-1970s aesthetic influences.
Age Estimate
Circa 1965-1980 based on the minimalist bezel design and the specific style of the safety clutch hardware.
Cultural Significance
Represents the 'professional attire' era of the mid-20th century where subtle gold accessories denoted status and attention to detail in corporate or formal settings.
Condition Notes
Very Good condition; slight oxidation or patina may be present on the pin stem. Gemstone surfaces appear free of significant chips or abrasions.
Value Estimate
Resale value approximately $85 - $150 USD. Value is driven by the 14K gold content and the vintage appeal rather than the gemstone rarity.
Care & Maintenance
Clean with warm soapy water and a soft cloth; avoid ultrasonic cleaners if the stone is epoxy-set; store separately to prevent the sharp point from scratching other jewelry.
