Platinum Hallmarking in India: Current Status and Future Plans

While gold and silver dominate India's precious metals market, platinum occupies a growing niche — particularly in premium jewellery and investment products. The BIS framework for platinum hallmarking exists under IS 2640, though its adoption and regulatory trajectory differ significantly from gold and silver.

Platinum in the Indian Market

India's platinum jewellery market is small compared to gold but has been growing steadily. The Platinum Guild International (PGI) has actively promoted platinum jewellery in India through its "Platinum Days of Love" and other campaigns, targeting the premium and bridal jewellery segments.

Platinum's appeal lies in its rarity (approximately 30 times rarer than gold), its white colour (naturally white, unlike white gold which requires alloying), its density and heft, and its hypoallergenic properties. However, platinum's higher melting point (1,768°C vs gold's 1,064°C) makes fabrication more challenging and costly, contributing to higher making charges.

IS 2640: The Indian Standard for Platinum

BIS has established IS 2640 as the Indian Standard specification for platinum and platinum alloy jewellery. The standard covers several purity grades:

The 950 grade is the most common for platinum jewellery worldwide, as it provides a good balance of purity and workability.

Current Hallmarking Status

Platinum hallmarking in India is currently voluntary. BIS-authorized hallmarking centres can test and certify platinum articles under IS 2640, but there is no mandatory requirement for platinum jewellery to be hallmarked before sale.

The voluntary platinum hallmark includes the BIS logo, the purity/fineness number (e.g., 950), and an identification mark. Unlike gold and silver, platinum hallmarking has not yet been brought under the HUID system, though this may change as the regulatory framework evolves.

Testing Platinum

Platinum is tested using the same analytical methods as gold and silver:

XRF spectrometry — The primary screening method. XRF can identify platinum and distinguish it from white gold, palladium, and other white metals. However, platinum's XRF spectral lines require specific calibration.

Fire assay — For definitive purity determination. Platinum fire assay differs from gold fire assay in the temperatures, reagents, and parting methods used, reflecting platinum's higher melting point and different chemical behaviour.

Not all hallmarking centres are equipped for platinum testing. The XRF calibration standards and fire assay procedures for platinum require specialised reference materials and expertise.

Challenges for Platinum Hallmarking

Small market volume — India's platinum jewellery market is a fraction of the gold market. This limits the economic incentive for hallmarking centres to invest in platinum-specific calibration and expertise.

Consumer awareness — Many Indian consumers are less familiar with platinum compared to gold. Awareness of platinum hallmarking standards is correspondingly limited.

Fraud risks — In the absence of mandatory hallmarking, there is a risk of white gold or palladium being sold as platinum, or lower-purity platinum being misrepresented. Mandatory hallmarking would address these risks.

Pricing complexity — Platinum prices fluctuate independently of gold, and the relationship between the two can invert (platinum has traded below gold in recent years). This adds complexity for consumers comparing precious metal purchases.

Global Platinum Hallmarking

Internationally, platinum hallmarking varies by country:

United Kingdom — Mandatory hallmarking for platinum articles above 0.5 grams, with assay office marks and fineness numbers.

Japan — The world's largest platinum jewellery market has voluntary hallmarking through the Japan Mint.

Vienna Convention — Platinum is covered by the Convention alongside gold and silver, with mutual recognition of hallmarks among member countries.

Future Plans

BIS has indicated interest in strengthening the platinum hallmarking framework. Possible developments include bringing platinum under the HUID system for digital traceability, expanding the network of centres equipped for platinum testing, eventually mandating platinum hallmarking as the market grows, and aligning Indian platinum standards with international conventions.

What Consumers Should Know

When purchasing platinum jewellery in India, ask whether the article is BIS-hallmarked under IS 2640, verify the declared fineness (950 is the most common for jewellery), request a detailed invoice specifying platinum weight, purity, and any gemstones, be aware that "platinum finish" or "platinum colour" does not mean the article is made of platinum, and consider submitting unhallmarked platinum to a qualified AHC for purity verification.

Platinum's Place in India's Precious Metal Framework

As India's hallmarking system matures — with mandatory gold hallmarking established, silver hallmarking launched, and bullion hallmarking under discussion — platinum represents the next frontier. While the market remains small, the regulatory foundation under IS 2640 exists, and the trajectory toward broader coverage appears clear.
