These are long shots, but here are two possible guesses from me:
1. Are you in the right ring? Many planets have A, B or even C rings. These are stepping outwards from the planet and show different brightnesses. Metallic rings are dimmer and can be quite narrow.
2. Have you accidentally got the things you want to collect in your Ignore list? Try looking in Contacts to see if there are good fragments greyed out.
