I bought this ring to wear with my wedding set.  I have a 2mm white gold band and wanted to add another white band on the other side of my engagement ring. I ordered a 2mm size 7.  The fit was perfect however, compared to my 2mm wedding band, this ring was more like 1mm.  I will keep it and wear it as a stackable ring on the other hand because no matter what, you cant beat the price for this little silver nugget!.  In fact, I just ordered a second one to wear with a twisted stackable.
