I make these rings from round sterling silver wire. Once I've made the ring I take the tip through a patterned rolling mill several times to give it the teardrop shape. This process gives it an organic, one of a kind look, almost a perfect teardrop shape.
Afterwards I saw the ring open and polish the ends so they will go through your piercing smoothly.
I get it goldplated in 24k gold in the thickest layer possible at a local plating business.
This is a twist open ring, if you look under care and sizes at the menu you can see how to open and close it correctly.
