Jaipur has become a jewellery manufacturing centre as well as a Gemstone cutting centre. The journey of Gemstone manufacturing began with a handful of artisans working on unpolished precious stones, which today, has turned into the largest industry, with more than 100 factories cutting coloured gemstone.
I have always been interested in knowing the procedure of a gemstone manufacturing, and during my recent trip to Jaipur, I had an opportunity of visiting Jaipur Gem factory, an endeavour of Lunawat Gems Corporation located in Sitapura Industrial area.
The company has manufacturing units with highly experienced artisans and craftsmen. All the gemstones are cut and polished in the factory using sophisticated tools and technology, maintaining strict quality control standards for proportion, polish, size, and shape.
With great enthusiasm, I began my factory tour, to understand, step by step manufacturing procedure along with Mr Shrenik Lunawat.
The detail explanation is as follows :
1) Rough Assorting
The first and the foremost step is the Assortment of Rough, this is a process, of checking the rough gemstone and identifying it piece by piece, to understand the best shape and size to be polished. Planning is done carefully, to achieve the best output to minimize waste and maximize the yield of the rough stone. This is a very important department, as a gemstone begins its journey of being transformed from a rough to a polished stone from here onwards.
2) Slicing – Getting rid of the unwanted inclusions by sawing through them.
3) The first step of Preforming – Here the Gemstone is given an overall shape by hand, making sure to grind more on the bad parts while saving the good parts of it.
4) Calibration – This process involves giving the semi-shaped piece a proper shape.
5) Final Preforming – In this process finishing touches are given to the stone, ensuring no difficulty may arise, during the Faceting/polishing process.
5a) Faceting: This process involves making facets in the stone with an assisted factoring machine with fixed indexes for each facet, great care has to be taken of each angle to make sure the stone shows maximum brilliance. This step makes sure that the stones are at its best before being set into jewellery.
5b) Polishing: this step is used for cabochons or spheres to give the stone a shiny smooth finish using a combination of polishing powders. This is a multi-step process, on every step, the polishing powder keeps getting finer to get the best possible polish without any scratches.
After detailed monitoring of the various procedure, a beautifully polished gemstone is ready to be set in the jewellery !!
