When diamond prices fell sharply in recent years, the fall did not just reshape the market — it exposed it. Sellers charging inflated markups had nowhere to hide. Then came a second disruption: lab-grown diamonds entered the mainstream, visually identical to natural stones, priced lower, and increasingly present in showrooms across India — often without buyers fully understanding what they were purchasing. The result is a market where trust is harder to find than ever, and where the question of exactly what you are buying — and whether you are paying a fair price for it — has never been more difficult to answer.
In that context, a business built on four generations of sourcing integrity is not just refreshing. It is necessary.
A Business Built on What Cannot Be Faked
Kunal Sanjay Jewels has been part of Delhi’s fine jewellery landscape for generations. Kunal is the fourth in his family to carry the business forward — and that continuity is not incidental to the brand, it is the brand. Four generations means this family has survived diamond booms and crashes, the rise of branded jewellery chains, and the entry of lab-grown stones. They are still here, still operating to the same standard, still earning the trust of clients who refer their children and grandchildren.
Part of what has kept that trust intact is structural — something most buyers never think to ask, but probably should. Most retail jewellers source their stones from a wholesaler or intermediary, each adding their own margin. By the time a diamond reaches your finger, it has passed through several pairs of hands, and you have paid for every one of them. KSJ operates differently. As a wholesaler, they sit closer to the source. Fewer hands means more visibility into what a stone actually costs, and more honesty about what the client should be paying. In a market where inflated pricing has long been the norm, that proximity is not a small advantage — it is a fundamental one.
The Standard That Does Not Change
“We source each diamond as if it is being sourced for family. Because that is exactly our target — to form one big KSJ family.”
— Kunal Sanjay, KSJ
In an industry where the gap between what is promised and what is delivered has never been wider, that sentence carries real weight. It means every stone is evaluated to the standard you would apply if a family member were wearing it — the question is never “what can we sell this for” but “is this genuinely worth what we are asking.” When diamond prices fall, as they have and will again, buyers who purchased through KSJ are protected by the fact that they never overpaid to begin with.
Built for the Buyer Who Knows What They Want — and the One Who Does Not Yet
Walk into KSJ and you will find two kinds of clients. The first arrives with a reference image, a stone specification, a vision that has been living in their head for months. The second arrives with a feeling — something about a diamond, a colour, a particular kind of piece — but not yet the language for it. KSJ is built for both. What they offer is not just access to stones — it is a conversation that begins with understanding what the client is actually looking for, which is often not exactly what they walked in asking for. The job, as Kunal sees it, is to listen first and craft second.
Their customisation capability makes this possible in a way few jewellers can match. Whether it is a solitaire setting that does not exist anywhere on the market, a piece built around a single hero stone, or an entirely original design sketched on a phone screen — KSJ can make virtually any piece a client envisions. This is not a side service. It is central to what the brand believes jewellery should be: personal, considered, and made to last.
A Range That Sets Them Apart
KSJ is not a single-category house. Their core offering — natural diamond solitaires, sourced with provenance and priced with the transparency that comes from sitting close to the source — is what most clients come in for. But the coloured gemstone collection is where the brand’s access really shows. Rubies from Burma — the deep pigeon-blood red that the world’s finest rubies are known for. Emeralds from Colombia, where the most saturated greens originate. Pearls fished from the wild, uncultured sea, with the lustre that cultured pearls cannot replicate. These are not stones you find in most showrooms. Getting them requires relationships and a supply chain built over generations. For clients with a specific stone in mind that is not in the current collection, KSJ will source it.
The Piece That Says Everything
There is one piece in the KSJ collection that stops people mid-sentence. A necklace and earring set built around over 300 carats of Colombian emeralds — deep green, saturated, the kind of colour that makes you forget there are other colours.
It did not happen quickly. Before a single stone was sourced, Kunal and his team spent 100 hours in concept work — sketching, revising, debating what the piece was actually trying to say. The answer they kept returning to: it should feel like wearing something the earth spent a million years creating. Then came the stones — each selected individually for depth, clarity, and the precise way it would sit alongside its neighbour, sourced through relationships that only exist because of decades of trust in the trade.
Then came the craft. Over 1,000 hours of meticulous handwork. Each diamond placed by hand. Each emerald set with the quiet certainty of someone who knows this piece will be worn at a granddaughter’s wedding someday.
“This set is more than just jewellery. It is a story of patience, passion, and precision.”
— Kunal Sanjay Jewels
It is also, in a single object, the story of KSJ itself.
For the Family Planning a Wedding
If there is one moment in life when jewellery truly matters, it is a wedding. The piece a bride wears on her wedding day is not chosen lightly — it is chosen to be remembered, photographed, and eventually passed down. The wrong choice is not just an aesthetic regret. It is a permanent one.
KSJ’s wedding offering is built around a truth most brides already know: they do not want what everyone else has. They want something that feels like them — a solitaire that sits exactly right, a necklace designed around a specific lehenga, a full bridal set where every piece is considered as part of a whole. Families come in with references — photographs, sketches, sometimes just a description — and KSJ works with them to design from scratch. The process is collaborative and unhurried. The result is jewellery that is entirely one of a kind, made for the person who will wear it and the generations who will inherit it.
You do not have to settle for what is in the showcase. At KSJ, the showcase is just the beginning of the conversation.
A Name Built to Last
Kunal Sanjay Jewels is based near Bengali Market in central Delhi — a fitting home for a business that has been part of the city’s fabric for generations. Walking in, you are not walking into a showroom. You are walking into four generations of considered choices, hard-won supplier relationships, and an unwillingness to compromise that has outlasted every disruption the market has produced.
In a market where too much is disposable, too much is approximate, and too much is sold on confidence that later turns out to be misplaced, KSJ is building something different: a name that means something, one piece at a time.
Because the best jewellery does not just mark a moment. It carries it forward.
