Gold and Garnets is something that is specfic to an era which isnt generally the Viking Age normally thought of as being post 793ad, anybody who was anyone was reconisable by the quality of their clothing an expensive commodity in a time when everything had to be done by hand... silk for example was a rarity and only worn by the very rich and at least one Scandinavian king went under his mound in a gown containing gold thread...

If you want somthing specific then that might be a sword with a silver inlaid hilt possibly with niello decoration for a wealthy man of a specific type, for warriors looking to join Cnuts Huscarls(1013ad)it was a requirement to become a member, that and owning a mail shirt....

It would a good question if you could tell the difference, I suspect in the hair.. Anglo-Saxons seem to favour short hair and mustaches and otherwise clean shaven unless old, possibly to some degree the clothes almost certainly the language and often but not always the religion, and Scadinavians likes Axes a lot.... but otherwise a knee length tunic, mail shirt, a conical or occasionally domed helmet, sword, spear and round shield would be normal during most of the age...

Your mistaking Harold Godwinson for Harold Hardrada see "King Harolds Saga" Snorri Sturluson, Anglo-Danes/Saxons better to call them English joined the Varangian guard after 1066...

norway,sweden,rus,constantinople,asia minor.
hardrada sure got around before stamford bridge.

Fought in battle at 15 died in battle at 51.... a true Viking King

hardrada fought with the varangian guard in a couple of battles in italy,against the normans and lombards.
would there be any real difference by this time between lombards in italy and normans?
(i hope its ok to ask in this thread)

p.s.
viking varangian guards.sounds like a neat set to make.
