Tiffany silver olive leaf ring - wide

The more I wore it, the more I felt that it would cut off my blood circulation one day, so I ended up going back to TIFFANY to exchange for a bigger size, and now it's much more comfortable to wear. I normally wear size 6 but for this one size 6 feels really tight. Size 7 is a bit too big for me but stays on okay when my hands are dry ( need to be careful when I wash my hands as it slides off very easily when my hands are wet). Would be perfect if it came in half sizes, but unfortunately this particular ring does not. I really like it and have decided to keep it although it's a bit too big (Better than being too small) for me.
