What specific type of Tiffany's jewelry should I present my future wife on our wedding day?

Women I need your help. I have a budget of $250-400. Bracelet, necklace, jewelry box. Any detailed help (ie. product numbers etc) would be great help! I want it to be noticeable as a Tiffany piece at first glance...like the Tiffany blue or their trademark name on it. Thanks!
