The Josefinas Blue Persian Salt flats are adorned with a beautiful piece of fine jewelry that is handmade from gold and blue topazes by master Portuguese jewelers. The Blue Persian Salt is one of the four pairs of flats in the 1001 Nights collection, also known as the Arabian nights. Retailing for approximately $4,000, the ballet slippers clock in as the most expensive ballet flat ever.
The brand notes, "Inspired by the rareness and beauty of this mineral, only found in Iran, Josefinas Blue Persian Salt travel in a box worthy of a jewel." Some believe the semi-precious blue topaz stone has mystical powers, like the ability to provide protection and bring fortune.
