Her fingers are so small! Initial purchase was a 5, sent back to Blue Nile for 3.25. She was sized at local jeweler this winter, 3 too tight, 3.5 too loose. The current size fits but I can pull it off with minimal resistance. Had her do the shake test and it did not fall off. Tends to spin as well. I do not want to resize in the middle of February in New England, would prefer to wait until the spring/summer. Any advice? Do they make temporary ring guards for such a tiny size? Thank you!
