Melania Trump

In 2004, the idea of President Donald Trump was still incredibly farfetched. But the man who would one day get to the White House was already a compelling and rich individual. He spent an estimated $2.3 million to gift his wife-to-be, Melania Trump, with a beautiful 15-carat emerald-cut jewel.

Ten years later, Trump invested a reported $5 million to give Melania the perfect 10th-anniversary gift: a new diamond, this time a sizeable 25-carat sparkler! Melania wore the impressive gift in her first official White House portrait, and the huge jewel makes for a definite attention-grabber.
