I am looking to propose to my significant other ASAP and we've found a 1.7 carat ring on Etsy from a company called Britain for around 5k, I am not sure if I can trust the company and want to know the best places to look for similar rings. I understand if I may need to downgrade carats at that price range but just to do not want to buy a fake ring from this company online. Any help would be greatly appreciated. Thanks!
