Earlier this year an amateur metal detectorist found the largest Byzantine hoard of gold sword and armour components (1500 pieces !!) in an english field. It contains mostly gold pieces, some with gorgeous garnet inlay work. It is hailed as one of the most important and astonishing finds from that period. I have not seen such beatiful sword work before, especially from so long ago. Too bad an entire sword was not part of the find, but there likely is a reason for it...
Here's a good site with explanation and many high quality photos (in the "artefacts" section):

The whole hoard has been evaluated at more the 3.5 million British pounds. Ant the finder will likely get half. Here are some pommel and hilt examples:
