I am newly engaged as of less than three weeks ago. After my fiance proposed, we went engagement ring shopping together. After going to multiple jewelers, we found a ring that I absolutely adore at Frost & Co, and we bought it. Before the purchase, we were measured for ring size -- I have very small fingers and was worried about having them size down a ring to fit. The representative at Frost told me that unlike all of the other jewelers that we visited, such as Jared's, Kay's, etc., they never size down rings but make them bespoke for the client. They measured me at a "perfect" 3.5, but when we went to pick up the engagement ring days later when it was ready, I commented that it felt a bit loose. They THEN told me, after it was already made and bought, that they can't size my ring down to smaller than a 3.5 because it wouldn't be able to hold the diamond. They said that they could give me plastic grips to put inside of it. I decided to take the ring without the grips to see how it went. However, after having worn it around, I can now say that it is definitely too big. Everytime my hands get wet, it just slides right off! I have left it in the box and have not even been wearing it as I'm afraid of it falling off my hand. I am very anxious about going back into the shop and complaining as I sometimes get panic attacks, and my fiance is overseas. We paid for this fancy ring that was supposed to be customized to my size. I don't want to give it back, and I don't know what to say to the company. What should I do? I could really use some suggestions.
