Princess-Cut Blue Topaz Stud Earrings in Silver-Tone Mountings

This pair of stud earrings features two princess-cut (square) gemstones, likely blue topaz or high-quality cubic zirconia, exhibiting a vibrant, electric blue hue with high clarity. Each stone is approximately 5mm to 6mm in size. The gemstones are secured in classic four-prong basket settings made of a polished white metal, likely sterling silver or a white gold alloy, though no hallmarks are visible from this top-down perspective. The facets of the stones are well-defined, suggesting a modern precision cut that maximizes brilliance and internal light reflection. The earrings are presented in a square, black flocked jewelry box with a velvet-like interior, which appears to be in good condition. The jewelry itself shows no visible signs of wear, stone chipping, or metal oxidation, suggesting they are either contemporary or have been meticulously maintained. The overall craftsmanship indicates a commercial jewelry grade, common in late 20th to early 21st-century retail. The uniform color and step-cut facets typical of princess cuts provide a clean, geometric aesthetic suitable for formal or everyday wear. Total carat weight is estimated between 1.5 to 2.0 carats combined, depending on the specific depth of the stones.

I have conducted a visual inspection of the Princess-Cut Blue Topaz Stud Earrings. The pair consists of two approximately 1.00ct (5-6mm) princess-cut stones exhibiting the characteristic 'Swiss Blue' saturation common in treated topaz. The stones are set in standard four-prong silver-tone basket mounts. Based on the lack of visible hallmarks and the style of the presentation box, I am valuing these as sterling silver decorative jewelry. The stones show excellent clarity and facets are free of abrasions, indicating the items have been well-maintained or are of recent manufacture. Market demand for semi-precious blue gemstones remains steady; however, because blue topaz is mass-produced and frequently irradiated to achieve this specific hue, rarity is low. Comparables in retail environments range from $50 to $150 depending on the brand. The primary factor limiting value is the material; if these were confirmed as white gold with natural aquamarine, the value would increase tenfold. However, the visual 'electric' saturation is more consistent with commercial topaz. Limitations: This appraisal is based solely on digital imagery. I cannot verify metal purity without a professional acid test or XRF analysis. Furthermore, while the stones appear to be topaz, I cannot rule out synthetic spinel or cubic zirconia without measuring the refractive index and checking for pleochroism using a dichroscope. To finalize a legal appraisal for insurance, a physical inspection to verify hallmarks and stone density is required.
