This spritesheet set features a high-fidelity renderings of several metal colored rings some with a large faceted gemstones or pearls, rotating 360° across 16 frames. Each row represents a distinct color combinations, showing the ring's elegance under dynamic lighting and rotation. (much to my old computers suffering)

While the spritesheets depict spinning picking an angle and using it for game graphics is also doable with the higher resolution captures.

All in ISO format (view angle)
