championship ring 3d model

"A highly detailed, realistic 3D model of a classic NBA championship-style ring, but without any NBA logos, team names, or basketball imagery. The ring has the same iconic silhouette: a large, rounded octagonal or cushion-cut centerpiece (table) with tapered, solid shoulders. The band is thick and comfortable, made of polished yellow gold. The top face of the ring features a large, clear rectangular plate. On this front plate, there is an engraved, bold serif or block-letter inscription: 'BDC'. The background of the inscription has a fine brushed metal texture. The rest of the ring's surface is covered in intricate, elegant arabesque or filigree patterns (swirling vines and leaves) in low relief, especially along the shoulders and around the main plate. The edges of the ring are beveled and polished. No diamonds or gemstones. No basketball texture. Render as a watertight, manifold mesh for 3D printing, with realistic metal material (gold)."
