I ordered this band in a size 4 to compliment a CZ solitaire from Bling Jewelry as a wedding set for when I don't want to wear my diamond wedding set. The ring was way too small. I had to send it back. I ended up upgrading to the 4mm silver band (which was cheaper that day), which was also smaller than a size 4 but I'm technically a 3.75 on my left ring finger, so it did work and I did keep it the second time around. Plus I think I liked the look of the 4mm better than the 3mm. The 3mm was very thin, as to be expected. The return was easy and fast. The new purchase also was easy and fast. No hassles from Bling Jewelry!
