My mother-in-law wants to buy an approximately 1 carat diamond ring for personal use, and also as kind of an investment.
Where would be the cheapest reputable places to buy one?
We would need one that comes with a certificate to show the clarity/quality. But can these certificates be trusted and compared easily? We are new to buying diamonds, so any advice on how to avoid the pitfalls and get a good deal would be appreciated.
Diamond rings are not a investment, they don't have good resell value, if you lose it or some one steal it, there goes your investment.
