According to an article published by ladbible.com, Sankalp Singh Parihar, from India, was on a train to Chennai a few years ago when a fellow passenger asked him if he wanted a special mango sapling for Rs 2,500 ($33). (R470)  Taking a gamble, he agreed. But after a few months, he started to notice something different about them.

Speaking to Vice, he said: "I did not know what the mango breed was but I named it Damini after my mother and planted it.   "I grew it [the sapling] like an ordinary mango plant, but a few months later, saw that it had developed a beautiful red colour."  And when people caught wind of his produce, Parihar said he was offered a huge amount of money for them.  "It was only when they offered me more than Rs 21,000 ($283) for it that I realised it was something valuable," he told the publication.

It turned out that what Parihar had bought from the stranger on a train was something called the Miyazaki mango, which have been known to sell for thousands at special auctions in Japan.  According to reports, the fruit originates from the Miyazaki prefecture on the southern Japanese island of Kyushu.  And it is taken very seriously, with it having to be grown in special conditions, using nets to suspend them in the air, to make sure the sugar content is just right and that each one weighs at least 350 grams.

It turns out that the mango is so rare and expensive, that Parihar had to hire security to look after his garden of mangoes.  Read the full article, where the entire story about these rare mangos is explained by clicking here.
