Viking Quartz Lenses
So, not only were the Viking people amazing jewellers, they were also remarkably innovative. These are magnifying lenses, carved from clear quartz. These sorts of lenses were often used to make some of their intricate jewellery, and the tiny rune charms they made. Whatever method they used, it was utterly incredible to get this kind of clarity and smooth surface from the clear quartz, without modern polishes.
