Multi-stone ring with cushion-cut iridescent gemstone

This piece of hand-held jewelry is a multi-stone ring crafted from a silvery metal, displaying a polished finish with minor surface wear and light scratching consistent with regular handling and use. At the center is a cushion-cut or radiant-cut primary gemstone exhibiting a striking play-of-color with iridescent flashes of green, purple, and blue, a visual characteristic frequently seen in treated stones such as mystic topaz or synthetic quartz variants, though the exact gemological composition remains unverified from visual inspection alone. The main stone is secured in a traditional four-prong setting. Flanking the central setting are split-shank bands adorned with a channel or pave-style arrangement of smaller, round accent stones that appear to be clear diamonds or cubic zirconia. There are no clearly legible maker's marks, hallmarks, or stamps visible in this photograph to confirm metal purity or specific brand attribution. The overall design suggests a contemporary or modern commercial jewelry style, likely produced in the late 20th to early 21st century. The identification of the materials and stones is based entirely on visual observation and is unauthenticated.

Based on what I can see in the photograph, this multi-stone ring features a cushion-cut or radiant-cut central iridescent gemstone, potentially a treated stone such as mystic topaz or synthetic quartz, secured in a four-prong setting. Flanking this are split-shank bands with small round accent stones that appear to be clear diamonds or cubic zirconia, set within a silvery metal showcasing minor surface wear and light scratching. However, I can't verify the exact gemological composition, metal purity, or brand attribution from a photo alone, as there are no clearly legible hallmarks visible. Assuming the attribution to a contemporary commercial jewelry style with treated center stones and simulated or genuine accent stones is correct, items of this type typically trade in the $150 to $300 range within the secondary retail market, depending on whether the metal is precious (such as sterling silver or white gold) and whether the accents are diamonds. If physical inspection reveals the piece to be a modern replica, unbranded fashion jewelry with base metals, or purely synthetic components, the value would likely drop to the $30 to $75 range. To confirm authenticity, material composition, and precise value, I would need physical inspection, hallmark verification, and scientific gemstone testing.
