most definitely NOT!! Sterling and fine silver are so cheap
for the amount you would want that whatever you use to hold the
stone, you must use silver, gold, or even surgical steel wire
where it goes through ear-flesh. Or any other flesh ..
Titanium or niobium are also safe, non-allergenic choices, if
your design can use these metals (which cannot be soldered, but
which CAN be brightly colored by anodizing). And don’t forget
platinum, though of course now we’re not talking cheap anymore…
