That is so rude! I have heard women say those things to one another too or comment, oh, "that's all he could afford then?" Once I was in a meeting and one girl said to another, "oh, my ring has a similar setting to yours, but mines a ton bigger!" WTH is wrong with people? If you don't have anything nice to say, keep your mouth shut!
Your current ring is very pretty- I really like the setting and the bands on top and bottom!
