A a super rare "Fancy Deep Blue" diamond weighing more than 20 carats was unveiled Wednesday from Botswana — the largest natural blue diamond discovery that has ever been made in the country. The marvelous diamond exceeds the clarity and purity its world-famous predecessor, the Hope Diamond. 

The oval-shaped diamond was discovered as a 41.11 carat rough stone. It was then cut and polished, retaining 20.46 carats.

Blue diamonds of such size are very uncommon and through out history have only sporadically been found.
