Pair of Round Brilliant-Cut Stud Earrings

This item is a pair of stud earrings featuring large, round brilliant-cut colorless stones. Based on the visual evidence, the stones appear to be high-carat diameter, likely measuring approximately 6mm to 8mm each. The stones are secured in multi-prong settings, appearing to be six-prong crown or ‘buttercup’ styles crafted from a yellow-toned metal, likely yellow gold or gold-plated brass. The metal shows a warm, lustrous finish with minimal visible oxidation in the prongs. The stones exhibit a significant amount of light dispersion (fire), though their slightly warm or yellowish tint and large scale compared to the hand suggest they could be high-quality cubic zirconia, moissanite, or possibly genuine diamonds if the setting is solid 14k or 18k gold. No specific maker’s marks are visible in the image, but the construction of the posts and the wire-style backings suggests a late 20th-century to contemporary manufacturing period. The condition appears to be excellent, with no missing prongs or visible chips to the facets of the stones. The scale and traditional solitaire design indicate a classic, timeless style aimed at maximizing the brilliance of the center stone. Professional testing for thermal conductivity and a microscopic hallmark check would be required to confirm the exact materials and value.

I have virtually examined this pair of round brilliant-cut stud earrings. The stones appear to be approximately 1.5 to 2.0 carats each, secured in traditional six-prong settings. The metal displays the characteristic luster of yellow gold, while the stones show high dispersion and internal fire. Visually, the condition is excellent with no signs of facet wear or prong fatigue. However, visual inspection alone cannot distinguish between genuine diamond, moissanite, or high-grade cubic zirconia. If confirmed as 14k gold with cubic zirconia, the value sits at the lower end ($150-$300). If the stones are moissanite, the value rises to $600-$900. Should they be confirmed as natural diamonds of G-H color and VS clarity, the value would exceed $15,000. For the purposes of this fair market estimate, I have categorized them as high-quality bridge jewelry unless proven otherwise. Market demand for classic solitaire studs remains consistently high, as they are a staple of contemporary jewelry collections. Comparables in the 'costume-to-fine' transition market show steady pricing. To provide a definitive valuation, a physical examination is mandatory. This must include electronic thermal and electrical conductivity testing to verify stone identity, a microscopic inspection of laser inscriptions on the girdles, and a chemical reagent or X-ray fluorescence (XRF) test to determine the gold purity of the settings. Provenance or a GIA/AGS laboratory report would significantly bolster the final appraisal figure.
