Ruby and diamond cluster earrings

This pair of cluster earrings features a classic floral or sunburst design, shown alongside a US dime for scale to indicate their small, delicate size. Each earring centers on an oval-cut, purplish-red gemstone visually consistent with ruby, measuring roughly a few millimeters across, secured by four prongs that appear yellow or gold-toned. Surrounding each central stone is a halo of small, round, white melee stones visually consistent with diamonds, set in a white precious metal mounting that creates high contrast against the red centers. The overall construction displays a traditional multi-stone cluster configuration frequently utilized in fine jewelry from various mid-to-late 20th century periods through the modern day. No maker's marks, hallmarks, or stamps are discernible in this photograph; therefore, metal purity (such as yellow or white gold) and the exact gemological nature of the stones remain entirely unverified without physical and microscopic testing. The surface condition appears generally intact, though minor wear and natural patina may be present upon closer inspection. The identification rests solely on visual characteristics of the stones and mounting style.

Based on what I can see in the photograph, this pair of cluster earrings features a classic floral or sunburst design utilizing oval-cut purplish-red gemstones visually consistent with rubies surrounded by small melee stones visually consistent with diamonds. I can't verify from a photo the exact gemological identity of the stones, nor can I determine the metal purity of the mountings, as no hallmarks or maker's marks are discernible. The estimated value range of $600 to $900 assumes that the central stones are natural rubies and the surrounding stones are genuine diamonds set in precious gold or platinum. This valuation reflects typical market behavior for mid-to-late 20th century multi-stone cluster earrings in good general condition. However, would need physical inspection to confirm material composition and stone quality. If physical testing reveals that the stones are synthetic or imitation, or if the metal is base or plated, the market value would decrease significantly, likely falling into the $150 to $300 range typical for costume or fashion jewelry of similar style. To establish a rigorous and fully supported valuation, what would be needed is in-person examination, hallmark verification, and gemological testing by a qualified professional.
