Welcome to Mercury Chains Co
Mercury Chains Co is the contemporary expression of a legacy that began in 1940 with Jagmohan Das & Co., one of North India’s most trusted names in the gold bullion trade. For over eight decades, our family has served as quiet custodians of purity, precision, and trust in precious metals.
What began as a wholesale bullion enterprise supplying high-purity gold to jewellers, investors, and institutions has now evolved with the same integrity and craftsmanship into a more personal offering.
In 2023, we launched Mercury Chains Co, a fine jewellery house specialising in elegant gold chains, bracelets, and timeless ornaments, crafted entirely in-house. By removing intermediaries, we offer our patrons the advantage of refined quality at unmatched value, rooted in our deep knowledge of metal, pricing, and detail.
Each piece is BIS hallmarked and HUID certified, and presented with full documentation to ensure transparency, traceability, and peace of mind.
Whether you are purchasing for beauty, tradition, or investment, our gold is exactly what it promises to be.

WhatsApp Cloud API & Meta
We use the WhatsApp Cloud API, a service run by Meta (WhatsApp). When you message us on WhatsApp, certain data is processed by Meta’s systems. Meta's privacy policies and terms apply to that processing — please see WhatsApp/Meta documentation for details. We do not control Meta's independent processing of data; we only control how we use the data we receive from the API.

- Meta (WhatsApp) as part of the API usage; Meta may log transactional metadata for its services.

We retain WhatsApp messages and related records only as long as necessary to provide our services, to comply with legal obligations, or to resolve disputes — typically up to 2 years unless a different retention period is required by law or our operational needs. You can request deletion as described below.
