A family friend only sells Hearts on Fire diamonds, but I have my eye on the White Flash ACA line. I can''t justify buying a Hearts on Fire, but still would like to patronize the family friend''s store by purchasing the setting there. Is it bad etiquette to purchase a diamond from another store and bring it the family friend for the mounting/setting? Any help would be greatly appreciated! Oh and just have to say for the thousandth time, these forums are a god send!
