Women Bridal Wedding Engagement Alloy Finger Ring Luxury Jewelry

First when trying to choose ring size, you have to choose 16, 17, or 18. I as American, have no idea what sizes these may be. I ordered a 17 and it is way too small. It has a pretty color but just not wearable due to size. This pic is taken on my left ring finger.

Took wayyyyyy too long to arrive,4 months in all.wont be ordering nothing else off this site.says shipping takes 14 - 21 days but took 4 months and 3 days instead.not happy as it was part of a birthday present a month ago

This is the third ring thst I have received lately that has been the wrong size. This one must be a size 4 or 5 when I need an 8 or even 7 fits my finger. It wouldnt even fit my grandaughter finger who ususlly wears a 6.
