Does anyone know where to buy wholesale or cheap either raw brass or oxidized brass/copper/silver open back prong settings in the sizes of 18x13mm, 25x18mm, 10x8mm and 14x10mm. i've searched the web and am having a really hard time finding anything at all besides the website vintagejewelrysupplies.com but they dont have enough items in stock for my needs......

 Any ideas anyone???

Have you tried Earthly Adornments?? They have some very unusual beads and findings, usually vintage, and lots of brass, filigree, etc.

www.earthlyadornments.com

Try eloxite.com 

The site is a little awkward - if you want a pendant setting, you look under pendants etc.  Fire Mountain actually has quite a few base metal settings. If you want to buy in very large volumes, you might contact Foreign Source and see if they can get what you need.

You might also want to post this under "Where Can I Find" - sometimes suppliers post there and may be able to help.

One more place to try - easternfindings.com 

 Try B'Sue's Boutique or jansjewels.com - Please google and they'll both show up. Much cheaper than some of the other sites.
