CLL's Services > Assaying & Hallmarking

2008 is a milestone year in Indian jewellery history. It is the year in which Gold hallmarking becomes compulsory. Each & every customer will have access to assayed & hallmarked (certified) gold jewellery.

With a view on the long-term, CLL set up a gold & silver hallmarking center in Indore - the first of it's kind in Central India. An investment of over INR 10 million was made in instrumentation alone - 

  • EDXRF, Laser assisted marking machine and fire-assay facilities.

Today, CLL's Assaying & Hallmarking Center has been approved by Bureau of Indian Standards. The center's quality systems are based on ISO/IEC 17025 and routinely particpates in inter-laboratory programs. 

What's amazing is the exceptionally rapid turnaround time which is often less than 12 hours. It is center's endevour to return all jewellery to the reuesting jeweller's on the same day even it means that we have to run extended / dual shifts. This is extremely beneficial to jewellery trade where the gold values fluctuate on a daily basis.
