About Chintamani
Chintamani is a Taluk Headquarters in the Indian state of Karnataka. Located on the Deccan Plateau in the south-eastern part of Karnataka. Chintamani is one of the well planned and developed Towns in the District of Kolar (before splitting) and presently Chikkaballapur. Chintamani is known for its Silk and Tomato production and their largest markets in Karnataka.
Word Chintamani refers to a precious stone or gem that's been documented since centuries in the Hindu Scriptures and Literature. However the naming of the town as 'Chintamani' doesn't have any relevance or relation with this gem. It's said that the town is named after a Marata chieftain Chintamani Rao.
