Thank you for your positive review of the quality of your ring!
With regard to the blank area at the bottom of your ring, this is noted in the item description as a 'small plain high polish area at the bottom of the band to allow for ring re-sizing if needed'. This is an important feature requested by our customers, as most people's fingers change size over the course of a lifetime, and having a defined sizing area makes it possible for our jewelers or a talented local jeweler to resize a ring without flattening the band where the ring is re-sized.
A ring which is the correct size will not turn on a finger, but rings can rotate around if they are being worn in too large a size. If you ever have an issue with your ring turning on your finger, you may want to have your ring resized to a smaller size, at which time you will appreciate that the ring has a defined sizing area.
We appreciate your comments, as they can be helpful in making other customers make informed purchase decisions.
