Hallmarked gold, diamonds chosen at source, margins kept honest: jewellery that earns trust the old-fashioned way.

About Us

A House Built on Trust

“Our finest advertisement has never been a shop window. It is the jewellery itself — and the people who keep returning for it.”

The name Manju Jain needs little introduction among Kolkata's diamond jewellery shoppers. For almost thirty years, the house has grown steadily — many times over — on the strength of one thing alone: relationships of immense trust with its customers. Most of our jewellery is bought by families who have bought from us before, and by the friends they bring with them. In a trade where trust is everything, we consider that our proudest achievement.

That trust is earned in the workshop as much as in the showroom. Every piece of Manju Jain jewellery is a considered union of gold and diamond, watched over at each stage of production. Our gold is uniformly 18k or 14k, and every single item is hallmarked before it is offered for sale. Our diamonds come to us directly from the manufacturers — where reputation and long relationship command the best prices — and each stone is physically examined by us before we accept it.

The making itself happens in Kolkata, the hub of diamond jewellery manufacturing in India, where the finest bench talent in the country gives our pieces their incomparable finish. And because we operate with the lowest possible overheads and keep our margins to the bare minimum, that quality reaches you at the best possible price — a promise we have kept for three decades.

Design, finally, is where the house looks forward rather than back. Our designers work constantly to bring customers the latest and best of contemporary jewellery — pieces that are unique, wearable, and desirable to any eye, whether the occasion is a wedding, an anniversary, or an ordinary Tuesday made special.

The Manju Jain Standard

Gold

Strong quality checks ensure every piece is uniformly 18k or 14k gold. Each item is hallmarked — and only then put up for sale.

Diamonds

Procured directly from the manufacturers, who offer us their best on the strength of reputation and relationship. Every diamond is physically verified before procurement.

Finish

Our production facility sits in Kolkata, the hub of diamond jewellery manufacturing in India — home to the best available talent, and the incomparable finish they give each piece.

Design
