Cluster gemstone cocktail ring

This is a statement cluster cocktail ring displayed on a white-gloved hand against a plain background. The ring features a prominent multi-stone floral or geometric cluster design on the top face. At the absolute center is a square-cut or princess-cut clear stone, which appears transparent and colorless, possibly white sapphire, cubic zirconia, or diamond, though this is entirely unverified from visual inspection alone. Radiating outward from the central stone is a halo of multiple marquise-cut purple stones resembling amethyst, arranged in a pointed petal formation. The setting is crafted from a silver-toned metal, likely sterling silver or white gold, with intricate milgrain or pave-style texturing along the broad shoulders of the band. There are no visible maker's marks, hallmarks, or stamps discernable in this image. The overall style is reminiscent of modern fashion jewelry or contemporary cocktail rings, though the exact age, metal purity, and gemstone composition remain completely unauthenticated. The item is in generally clean condition with bright stones and no obvious structural damage visible.

Based on what I can see in the photograph, this is a striking statement cluster cocktail ring featuring a central square-cut stone surrounded by a halo of marquise-cut purple stones in a floral or geometric arrangement, set in a silver-toned metal with textured shoulders. I cannot verify from a photo alone the metal purity, whether it is sterling silver or white gold, or whether the stones are precious gems such as diamonds and amethysts or more accessible alternatives like cubic zirconia and synthetic crystal. There are no visible maker's marks or hallmarks discernable in the image. My valuation assumes the piece is crafted in sterling silver with genuine semi-precious and accent stones if the attribution to a fine fashion jewelry category is correct. Similar contemporary fashion and cocktail rings typically trade in the $150 to $300 range in the current retail market, driven by demand for bold, decorative statement jewelry. However, if physical inspection reveals the metal is base metal and the stones are simulated, the market value would realistically decrease to the $25 to $50 range. To confirm the actual materials, value, and authenticity, I would need physical inspection, hallmark verification, and gemological testing.
