I found an article on the top 10 most expensive shoes in the world. Six of them were designed by Stewart Weitzman. He teamed up with jeweler Le Vian to make this pair.
They have 185 carats of tanzanite and 28 carats of diamonds. At the time the article was written, no one had worn them yet.
The best part is that they would totally match that replica of the The Heart of the Ocean you bought in 1997.
Price tag: $2,000,000
