3. Densuke Black Watermelon
Once a “Densuke Black watermelon” that weighed 17 pounds was sold for $6,100. What makes this a very expensive fruit is not hard to answer. Top of the list is it’s production – it is only grown in a Japanese Island and it’s harvest is done once a year which Yields to a total product of just a few dozen of those watermelons. The sweetness, crispiness and the hardness is almost perfect.
