Silver-toned cluster ring with faceted stones in a brutalist starburst style

This ring features a complex, tiered starburst or 'cluster' design, consisting of a central large faceted clear stone surrounded by radiating textured metal arms. These arms terminate in smaller faceted clear stones, varying in size and orientation. The metal appears to have a silver-toned finish with a notable granular or cast texture throughout, which is stylistically consistent with modernist or mid-20th-century brutalist costume jewelry. The central stone is round-brilliant in cut and sits within several prominent metal prongs. The smaller accent stones appear to be roughly prong-set or glued into small floral-shaped metal cups at the end of the radiating spurs. The overall metal surface shows some signs of wear, including possible minor pitting or tarnish, and the texture suggests a base metal casting rather than high-polish fine metal. Some slight discoloration is visible in the smaller stones, which may indicate aging or material degradation typical of rhinestones or glass. No hallmarks or maker's marks are visible in the provided image; therefore, the attribution remains speculative and based solely on the visual aesthetic of the piece. The construction and style suggest it could be a piece of vintage costume jewelry from the 1960s or 1970s.

Based on the provided image, I am examining a silver-toned brutalist-style cluster ring featuring faceted clear stones. The cast texture and starburst design strongly suggest mid-20th-century costume jewelry, likely from the 1960s or 1970s. However, based on what I can see, there are no visible maker marks, so this attribution remains a hypothesis. I cannot verify the exact metal composition or stone material from a photo; physical inspection would be needed to determine if the stones are glass or synthetic and if the metal has any precious content, though the texture suggests a plated base metal. The value estimate of $20 to $45 assumes this is a vintage, unmarked costume piece of the era. The condition shows visible wear, including minor pitting and some discoloration to the smaller stones, which lightly impacts the value. The market for mid-century brutalist costume jewelry remains active among vintage enthusiasts who appreciate the bold aesthetic, though unmarked pieces do not command the premium of signed designer items. If this item were to bear a mark consistent with a known designer of the era upon closer physical examination, the value could increase. Conversely, if it is a modern piece in the style of the 1970s rather than a true vintage item, it would fall toward the lower end of the range. An in-person inspection and material testing would be necessary to further refine this estimation.
