Hallmarking for Temple and Antique Jewellery: Special Considerations and Exemptions

India's jewellery tradition spans thousands of years, encompassing temple jewellery, antique heirloom pieces, and traditional craft styles like Kundan, Polki, and Jadau. The mandatory hallmarking framework recognises that these categories require special consideration due to their historical, cultural, and technical characteristics.

Exempted Traditional Jewellery Styles

The BIS mandatory hallmarking order specifically exempts Kundan, Polki, and Jadau jewellery from the hallmarking requirement. These traditional Indian jewellery forms involve setting uncut diamonds (Polki), gemstones, and glass in gold using lac (a natural resinous adhesive) rather than modern prong or bezel settings.

The exemption exists for sound technical reasons. XRF testing measures surface composition to a depth of 10–50 micrometres. In Kundan and Jadau work, the gold surface is often covered with lac, stones, and meenakari (enamel), making standard surface testing unreliable. Removing the stones and lac for testing would destroy the intricate craftsmanship that defines these styles.

Temple Jewellery

Temple jewellery — traditional designs inspired by South Indian temple architecture and deities — is not automatically exempt from hallmarking unless it falls under the Kundan/Polki/Jadau category or weighs under 2 grams.

However, temple jewellery presents its own challenges for hallmarking. Heavy antique-style pieces may have complex construction with multiple soldered joints, each of which can affect overall purity. Traditional temple jewellery reproductions made by modern manufacturers can be hallmarked through the standard process.

For actual temple donations and religious articles — gold jewellery adorning deities in temples — hallmarking is not required. These articles are not being "sold" in the commercial sense and fall outside the scope of the mandatory hallmarking order.

Antique and Inherited Jewellery

Inherited or antique jewellery presents a unique situation. These pieces were often made before the hallmarking era and may carry traditional markings, jeweller stamps, or no purity marks at all. Under current regulations, resale of antique jewellery does not require hallmarking if the jewellery is sold between individuals in a private transaction. However, if a jeweller purchases old gold for resale, the refurbished or reprocessed jewellery must be hallmarked before it is sold to a new consumer.

Purity Testing for Heritage Pieces

Consumers who want to verify the purity of inherited or antique jewellery can submit it to any BIS-authorized hallmarking centre for consumer testing. The XRF test is non-destructive and provides a purity reading without damaging the article. This is particularly useful for insurance valuation, estate settlement, and personal knowledge.

However, XRF results on antique pieces should be interpreted with care. Historical jewellery may have uneven alloy distribution, surface patina that affects readings, or historical solder compositions that differ from modern standards. In such cases, testing at multiple points on the article provides a more representative picture.

Meenakari and Enamel Work

Meenakari (enamel work) jewellery from Jaipur and other centres involves applying coloured enamel to gold surfaces. The enamel coating can interfere with XRF surface readings. Testing must be conducted on exposed gold surfaces, and the hallmark must be placed on an area that does not disrupt the enamel design.

Special Handling Requirements

When heritage or delicate jewellery is submitted for testing, hallmarking centres must take additional care. Experienced centres handle such pieces individually rather than in bulk batches, conduct testing on areas that minimise any impact on the article's appearance, and select marking locations that preserve the design integrity of the piece.

Cultural Significance and Practical Compliance

India's hallmarking framework demonstrates a thoughtful balance between consumer protection and cultural preservation. The exemptions for Kundan, Polki, and Jadau recognise that forcing standard hallmarking on these traditional forms would harm the craft without meaningfully improving consumer protection, given the technical limitations of testing these articles.

For jewellers dealing in both hallmarkable and exempt categories, maintaining clear documentation of which articles fall under exemptions — and which must be hallmarked — is essential for compliance. Consumers purchasing exempt jewellery should request detailed invoices specifying the declared purity, even though a BIS hallmark is not present.
