I have been sourcing for a diamond ring for a while and only chanced upon this site recently. This is really an amazing site with so many nice and helpful people.
I have a question on diamonds that till now I have yet to get a satisfactory answer from the local jewellers. Here''s the question:
If I were to buy a diamond ring, how can I be sure that this is not a trade-in ring especially when a lot of vendors has some form of trade-in program. Can I actually make an educated guess by using the date of the diamond certification? Is that the best I can do?
Hope the many experts around can shed some light on this. Thank you.
