Passion for Innovation Excellence in technology
Hallmark Twin

SLTL Group offers total technology solutions for diamond manufacturing, including diamond analysis and planning, processing, blocking and polishing as well as safe diamond trading. Hallmark Twin is the double-sided all in one Diamond Processing System doing Table Sawing, Crowning, Bruiting and Cone Blocking with one time fixing of the stone. This machine saves time & increase the productivity.  This provides you with more systematic production cycle with error-free operations. Hallmark twin is the 4th generation laser processing machine with inbuilt software for laser beam stability & robotic CNC control features. These are the new generation robots for diamond processing which will help redefine laser operations in the diamond industry, with the potential to produce almost 80% of the Work.

Ultra Modern Software

The most Progressive & easy to understand software is very straight forward. It is being designed to decreases the man-machine intervention significantly which eventually results in minimum possible human errors. software packagenot only helps in reducing the risk of damaging the stone but also automatically sets optimized laser parameters based on the size of a diamond.
