HALLMARKING

The insignia of being unrivalled in the world that resonates
a glistening transcendence.

Hallmarking

The systematization of the structure enables us to give you the best. Hence, before every piece undergoes a hallmarking process, we analyze them according to the Bureau of Indian Standards (BIS) guidelines for manufacture of gold jewelry as per IS-1417 and IS – 2112, respectively. Moreover, we consult the client to supply us with maximum information regarding their items, before segregating it into lots, so as to maintain transparency. This is also essential to get the most representative samples from a variety of traditional Indian jewelry which is intricate in its design and made out of multiple components soldered together.

TECHNOLOGY

Inscribing an official mark issues confidence in the product being offered. Hence, at GGC, we hallmark every gold jewelry with CNC Laser Marking machine, authenticating the purity through a non-impact method which does not cause sinking or bruising damages to items.

STANDARDIZATION

Our selection is as careful as the product that leaves GGC, with their ultimate goal being satisfaction of the customers. Therefore, a few of the chosen pieces out of each lot are scraped from appropriate locations based on their design/manufacturing criteria. The scrapped gold/silver is then accurately weighed on precision balance with 0.001/0.002mg accuracy and subjected to fire assaying (in case of gold) and gravimetric cum Potentiometric Titration method (in case of silver) as per the applicable Indian Standards specification: IS-1418 or IS-2113.

Once the fineness of the samples is found as per the declared purity, the representative jewelry/artefacts lots undergo hallmarking. Each BIS hallmarked bars are invariably carrying serial numbers and the stamp to create a difference from the normal production bars, for the naked eye. We have always been a trend setter and have demonstrated at all possible opportunities reflective in being promoted as a crucial turn in the trade.
