I need help FINDING and buying a promise ring for my girlfriend!
This is kind of embarrassing but I don't know much about jewelry at all. It you wanna skip the background, then skip the next paragraph lol
You see, I've been dating my girlfriend for a while, but she's studying abroad in another country and I never see her. After a while we can finally afford a shared vacation together this summer, and I really want to get her a promise ring. Maybe it’s stupid, but I want to wait to propose until we are financially secure enough to, not to mention when we are living together and more comfortable. This leads me to my problem:
I don’t know any trusted jewelers, and she likes a very VERY particular style of ring. (I’ll leave references below) I was hoping to get her a silver ring with a leaf design, (she doesn’t like gold) and a gem that’s green (her favorite color), or a something clear, preferably a real gem, not necessarily a diamond but I’m not opposed of that depending on the price. (If the ring is partially customizable that’d also be perfect but it’s not necessary) I don’t want to get scammed, but unfortunately my area doesn’t have good jewelers around, so it’ll likely have to be an online purchase.
**I need trusted websites and jewelers that’ll have something like this. Does anyone have suggestions?
I have a picture of rings she sent me that are her style, which I will attach under this. Lastly, when she went to get her finger measured apparently they were stock sizes? She said (direct quote from text) “I’m 6.03cm, it’s a little larger but the one before was 5.9cm and it was too small, the lady said fingers swell so it’s better to get a little bigger.”
Thank you so much for your help!
