Pair of blue cushion-cut gemstone earrings in a halo setting

A pair of drop earrings featuring two vibrant blue, cushion-cut gemstones, stylistically consistent with Swiss blue topaz. Each stone is set within a halo of small, clear accent stones, which appear to be consistent with diamonds or white sapphires. The metal is silver-toned, which could be white gold, platinum, or sterling silver, though no hallmark is visible in the provided image. The earrings are suspended from lever-back or huggie-style hoops that are also embellished with small pavé-set accent stones along the front. The main gemstones feature a checkerboard facet pattern on the crown, enhancing light reflection. The items are presented in a dark-colored, possibly velvet-lined jewelry box with a gold-toned metallic rim. No maker's mark or brand signature is discernible. The overall design is consistent with contemporary fine jewelry styles common in the late 20th to early 21st century. The condition appears to be good with no obvious chips to the stones or significant tarnish observed from this perspective. Because no stamps are visible to verify the metal purity or stone carats, this identification remains a visual hypothesis subject to in-person testing.

I have examined the image of the blue cushion-cut drop earrings. Based on what I can see, the design consists of two vibrant blue gemstones featuring a checkerboard facet pattern, surrounded by a halo of small clear accent stones. The metal displays a bright silver-toned finish. I cannot verify the metal purity or stone carats from a photo alone, as no hallmarks are visible; however, the style is consistent with a hypothesis of sterling silver or white gold set with Swiss blue topaz and white sapphires or cubic zirconia. My value estimate of $150 to $450 is based on the assumption that these are high-quality sterling silver or low-karat white gold settings with genuine semi-precious gemstones. This range reflects general market demand for contemporary fine jewelry of this aesthetic. The value is highly dependent on material verification; I cannot determine if the stones are natural, treated, or synthetic without an in-person physical inspection and gemological testing. If the metal were confirmed as $14k or $18k gold and the accent stones as natural diamonds, the value would likely increase significantly. Conversely, if the materials are revealed to be base metal and glass or crystal 'in the style of' fine jewelry, the value would likely drop below $50. To confirm these findings and provide a more precise valuation, it would be necessary to perform a professional acid or XRF metal test, a thermal conductivity test on the stones, and a close-up inspection for maker's marks or provenance documentation.
