Specific Instructions
for Submission of Jewellery for Hallmarking:
|
-
Before tendering
jewellery for hallmarking, from each lot (either
manufactured by same Gold smith or of similar design/Technology) a representative sample must be fire
assayed (destructive sampling) to confirm the fineness
for which is to be hallmarked. A record for the same is
essential to ensure that the jewellery being sent for
hallmarking meets declared purity. -
Hollow and studded
Jewellery is
not normally accepted for hallmarking. Hence it is advised
to send jewellery in semi finished condition (before studding)
to avoid any damage. -
Each piece of jewellery
must have an identification logo (jeweler's logo) and
the year of manufacture (Code Letter as decided by
Bureau of Indian Standards
e.g. letter 'A' denotes Year 2000 which represents the
year of hallmarking, the current code letter 'E' denoting
year 2004). -
Ensure that there is a
suitable provision on the piece of jewellery where hallmarks can be
put. If this is not the case, provide
with soldered strip at suitable place on the jewellery on which hallmarking can be
done. -
When jewellery being
sent for hallmarking is manufactured by different
artisans, segregation of the articles is to be done in
different lots for each artisan. This is to be specified
in the Issue Voucher so as to make sampling easier. -
The jewellery being sent
must be properly packed and sealed. It must also
accompany with it a detailed list of items, quantity and
weight. -
A sample format of the
Packing list to be attached in duplicate with the
package can be viewed by clicking on the hyperlink. NOTE:
It is necessary for the Jewellers to cover all the details
mentioned therein. -
The jewellery sent must
be insured for the period, for which it is in transit. -
Hallmarking Price list can be
viewed by clicking on the hyperlink.
-
Selection of minimum 10%
of total jewellery articles for scrapping from various
spots on the jewellery is done. Once scrapings meet to
the declared purity only then 100% of the lot to which
it represents will be hallmarked. -
In the event the sample
fails to meet the declared purity, a Lower Cartage or
Reject mark on each piece is put after informing the
client. However, the entire rejected lot will be charged
as per the attached price list.
