Ratti (unit)

Gold coins excavated from southeast Asia have been analysed as following the ratti based weight system as well.

The ball weights from jeweller's hoard discovered from Taxila conform to the 32 ratti standard also called Purana by Kautilya, while the Mathura weights (Dated from 1st century BC-2nd century AD) with Brahmi numeral 100 (100 svarna or 100 karsha) conforms with the new svarna standard.

[3] The Mughal empire employed Ratti as a unit of measure for the weight of precious stones such as diamonds.

Around 1665 the Shah's son, Aurangzeb, showed a diamond to the famous jeweler and world traveler Jean Baptiste Tavernier.

At that time Tavernier wrote in his Six Voyages: "The first piece that Akel Khan (Chief Keeper of the King's jewels) placed in my hands was the great diamond, which is rose cut, round and very high on one side.

Indus weights were based on binary multiples of Masha, which was equal to 8 Ratti
''The Great Mogul Diamond'' described by Tavernier weighed 319.5 Ratti
