A: The bad news is that we're limited to the stone sizes that the manufacturer offers. The good news is that I can get this ring in a few other stone sizes; 7 mm through 11 mm. Which stone size do you need? Also, if you haven't read the info on Ring Sizing, please do so. If you can tolerate a quarter size variation in finger size, you may be able to order a stock size. If you need a true finger size, it may or may not be available as a "stock" size, but is always available as a custom size.
