The world's most expensive mango, known as 'Miyazaki' and priced at around Rs275,000 per kg (€3,000) is now being showcased in a three-day-long Mango Festival in India. Farmers in the state of West Bengal grow the expensive variety, named after a city in Japan. Although the variety was first developed in California, it boomed after it was brought to Miyazaki in Japan in the 1980s.
These 
mangoes, also known as 'egg of the sun' in Japan, and 'red sun' in India, have a distinct purple color as they bud, and turn a brilliant bright red when they ripen. The fruit came to West Bengal when a local first planted a seed near a mosque. The mosque then auctioned the fruit and used the proceeds for development of its facilities. It is now grown in other farms around the region.
