Studio glass decorative platter on metal stand

This decorative art piece features a large, circular glass platter displayed vertically on a custom black metal stand. The glass platter exhibits a vibrant, multicolored abstract design with dominant concentric rings and swirls of bold red, bright yellow, cobalt blue, and pale green, set against a dark translucent or opaque background that frames the composition. The surface of the glass is glossy, smooth, and reflects ambient light, displaying depth and layering characteristic of studio glass techniques such as fusing or layered blown glass. The metal stand consists of a rectangular flat base supporting a curved, cradle-like arm structure that securely holds the heavy platter upright for display. There are no visibly discernible signatures, maker's marks, or stamps apparent from the visible angle of the photograph, leaving the exact maker and date of production unverified. The overall aesthetic is consistent with contemporary decorative art glass from the late 20th or early 21st century. The piece appears to be in good overall condition with no obvious chips, cracks, or structural damage visible in the image, though physical inspection would be required to fully assess wear or minor surface scratches. The identification rests purely on visual characteristics of the materials and form rather than any documented provenance or legible manufacturer markings.

Based on what I can see in the photograph, this decorative studio glass platter on a metal stand exhibits vibrant multicolored abstract concentric rings and a glossy finish consistent with contemporary art glass from the late 20th or early 21st century. I cannot verify from a photo whether the piece has an undocumented maker's mark or signature, as none are apparent from the visible angle. I would need physical inspection to confirm the weight, exact glass-forming techniques, and minor surface wear. The estimated value range of $300 to $500 assumes the piece is a quality example of contemporary studio art glass. General market demand for decorative art glass remains steady among interior designers and collectors of modern aesthetics, though individual pieces fluctuate based on provenance. If physical inspection reveals this item to be a mass-produced replica, a copy, or created merely 'in the style of' studio glass rather than an artisan-crafted piece, the value would likely drop to the $50-$100 range. To fully understand its market position and potential attribution, an in-person examination by a specialized glass expert and documentation of provenance would be required.
