I am in a search for a good diamond. Have been checking some diamonds at stores and see that an Ideal cut diamond has the best glimmer. I am curious with a budget of around $4000, can I go with a not so Ideal diamond and still get a good bang for the buck with a Very Good cut diamond. Also clarity and color what is the lowest I can go with and not see anything with the naked eye. I am putting this diamond on an 18k gold ring so I dont think I need to go with colorless or anything like that. Advice from experience people out there is greatly appreciated. Thanks.
