Vortex medallion is a type of chainmaille weave, which makes wonderful earrings and pendants. It's a combination of a helm weave with a mobius loop suspended inside -- very cool! While many of these are on the larger size (around 1" in diameter), the aluminum rings make them surprisingly lightweight. If you have a color combination you'd like, please email me and I'll see if I have the rings I need to make it!
