This morning we cleared up what I hope was the new website's last little bug. Let us know (here in the comments or using the contact us form) if you find anything that isn't working properly or you have any problems, or information is missing somewhere.
We're adding imperial sizes to our metric lineup. You can see the first ones listed here, on 16g Round Argentium. We're adding these as they're needed, so if there are imperial ring sizes you'd like to order, please let us know and we'll add those next.
