This is the largest of the currently rare rare blue diamonds. Its weight is 45.52 carats or almost 9.10 grams. It is set in a precious necklace, where it is surrounded by smaller transparent diamonds. The cost of "Blue Hope" is estimated at $ 350 million and, as is usually the case with jewelry of similar value, this most expensive blue diamond has changed the owner more than once, so even a legend has appeared about the curse imposed on the stone.
