RAPAPORT… A technology provider part-owned by De Beers has unveiled an automated cutting machine that, it claims, will significantly speed up diamond manufacturing and reduce costs.

Synova’s DaVinci system is the market’s first automated instrument that can produce all 57 facets of a round brilliant diamond in one process, the Swiss company said Thursday. The user only needs to perform one final polishing stage to finish the stone.

“Several cost-, skill- and labor-intensive steps in the polishing phase, such as crown and pavilion blocking, girdle bruting or recurrent quality checks, become redundant,” noted Bernold Richerzhagen, Synova’s founder and CEO.

The machine, currently intended for rough stones from 0.50 to 10 carats, gives manufacturers increased flexibility to adapt their production levels to business needs, such as seasonal demand, Synova explained.

It also gives better symmetry and a higher and more predictable polished yield, and uses water-jet technology to reduce the risk of diamond-cracking, the company asserted. It’s based on its existing DCS 50 cutting machine.

De Beers bought a 33% stake in Synova in 2015, pledging to work with the company to develop a fully automated cutting-and-shaping solution. The miner has made diamonds available for some of the machine testing.
