Does anyone know where to buy:
Thick walled sterling silver tubing (big enough to set 5mm gems
I do, thanks to this very forum!
Metalliferous has thick-walled silver tubing in a range of sizes and
they even tell you what size of stone each is suited for. Just go to
their website (metalliferous.com) and select the silver category,
then scroll down to near the bottom of the page and click on tubing.
Think maybe the second or third page is where you'll find what you
need. Have fun!
