I''m so happy to have found this website! Buying diamonds is the most confusing thing ever. I am looking to upgrade my diamond. I''m searching for a 1.0 ct emerald cut (but honestly would be absolutely thrilled to get a larger stone!)to replace my 0.50 ct stone. I''ve been on this website for the past several hours doing searches. I''ve read and read and honestly have discovered so much more on this website than from any salesperson at the jewelers (we have been to four). So much to consider! Our budget is up to $5500 and we (my husband and I) are hoping that is reasonable. Please advise...from what I read...you guys are awesome! Thank you in advance.
