[Source] Pipe-Cut Gold Rings

I am in need of some gold ring blanks. Here are the specific
dimensions: Straight Pipe style bands with flat inside and outside
profiles. I would like to be able to select a range of ring widths
from 5 to 8 mm. I would also like a minimum thickness (inside to
outside) of 2.0mm. These can be unfinished pieces as I will be doing
extensive manipulations and refinishing of the final designs. 14K
and/or 18K (possibly platinum, but later on that) Thank you for any
and all help.

Daniel, One the best known ring blank co.'s is http://www.jcnordt.com
They can supply just about any requirements. I’v also bought the same
from Johnson Matthey in Canada. Better price but significantly larger
minimum order size. They are the ones to use though if you plan on
supplying the gold yourself (toll transfer) instead of buying it from
the producer along with the labor charge.
