You can see the rings in my shop or on Etsy.
And here is the best I can figure the 2016 USPS postage rates are.
Lots of changes besides just the rates.
Commercial rates are lumped from 1-8 ounces.
International like more than doubled!!!
Under 3 ounces, retail pricing is less than commercial rates.
Using Click 'N Ship (printing postage from the USPS website) no longer gets you commercial rates.
If you use Etsy calculated, make sure you've selected "commercial (aka Etsy) rates" or "retail rates" so your customers get charged appropriately. You find this option at the bottom of the overall shipping profiles page. [Note: there seems to be an Etsy bug/glitch at the moment whereby if you have "commercial rates" selected, your customers are still being charged "retail rates". I hope they fix that soon.]
