Modernist-style white metal earrings with inset stones

This pair of earrings features a contemporary modernist design, characterized by two rectangular sections with a soft matte or brushed finish. Each rectangular face contains a small square-inset clear stone, appearing consistent with diamonds in a star-set or flush-mount style. The metal presents as a cool-toned white gold or silver-colored material; the owner suggests these are white gold, though this cannot be confirmed without professional metallurgical testing. One visible earring back is stamped with '750', a mark consistent with 18-karat gold purity, and bears a partial maker's mark that the user identifies as 'stern', potentially referring to the jewelry house H.Stern. All such markings are treated as hypotheses and are subject to in-person verification as they appear in a photographic context. The earrings appear to be in good condition with minor surface abrasions consistent with gentle handling. The craftsmanship displays clean geometric lines and precise stone setting, reflecting highquality contemporary manufacturing. These items are presented in a dark-colored jewelry box with a cream-toned interior, which is unbranded in the visible frame.

Based on my visual analysis of the provided image, these earrings appear to be modernist 18k white gold studs inset with small diamonds. The owner reports a '750' gold stamp and a 'stern' mark. While these markings are consistent with the jewelry house H.Stern, I must treat this attribution as a hypothesis. I cannot verify the metal purity or stone quality from a photo; physical testing is required to distinguish white gold from silver or plated metal and to confirm if the stones are natural diamonds. My estimate of $1,200 - $1,800 is based on the assumption that the 'stern' attribution and 18k gold content are accurate, as contemporary designer jewelry from established houses commands a significant premium over generic pieces. This valuation reflects current market demand for high-quality geometric minimalist jewelry. However, this estimate is contingent upon the items being verified as produced by the attributed maker. If physical inspection reveals the earrings are unmarked, lower-purity gold, or by an unknown maker, the value would likely drop to the $300 - $500 range based largely on the intrinsic weight of the materials. To confirm this appraisal, an in-person examination by a certified gemologist and metallurgical testing are necessary to validate the hallmarks and stone authenticity. Documentation of provenance would further support the higher valuation.
