The House · Delhi NCR
A modern bespoke diamond house, built by two people on one shared belief — that a piece should be imagined around the person who will wear it, not chosen from whatever was already made.
The House
Co-Founder & Brand Vision
Stuti Aggarwal is the eye behind the House. How a piece should sit on a hand, which stone earns its carat weight, when a design is finished rather than merely complete — those are her decisions.
PEXA DIAM began with a simple conviction: that nobody should have to compromise on the jewellery they actually wanted. Not settle for the stone that happened to be in the tray. Not accept a design because it was the one already made.
Co-Founder & Strategic Foundation
Mukul Aggarwal built the ground the House stands on. The conviction to begin, the structure to keep going, and the long view that turns an idea into something with a future — that work is his, and most of it is invisible in the finished piece.
He brings a belief in long-term value, in transparency, and in relationships that outlast a single purchase. It is the counterweight to a business that could otherwise be run on taste alone, and it is why the terms of buying here are written down rather than negotiated.
Different perspectives. A shared vision. One House.
Why the House exists
“I wanted women to stop compromising on the jewellery they truly wanted.”
Take mining out of the price and the same specification costs a fraction — which means the money can go into carat weight, or into a fancy colour that would be near-unobtainable mined, or simply stay in your pocket. That is the whole argument, and everything else here follows from it.
Pexa Diam exists to sell lab-grown diamond jewellery without the theatre that usually surrounds it. That means answering the awkward questions in writing rather than in a showroom, publishing the terms including the parts that are not flattering, and handing over an independent laboratory report you can check yourself.
It is a small house and it is not trying to be a large one. Every piece is made to order, which is slower and less convenient than holding stock — and it is the only way to make something to a particular hand, in a particular metal, around a particular stone.
Stuti Aggarwal spent seven years in the corporate world before moving into fine jewellery. The house was started with the family behind it, and it is run out of Gurugram.
What we stand for
Every centre stone carries an IGI report, and you can verify the report number on IGI's own site before you pay us anything. Prices are broken into the gold, the stones and the making charge, so you can see where the money goes. Our exchange and return values are published plainly, and where a condition attached to them is still being settled we say so rather than implying it is decided.
Nothing is made before somebody asks for it. Every piece is made to order in Delhi NCR, in your size, in the metal you choose, over three to eight weeks depending on how complicated it is. You get photographs as it progresses rather than silence and then a box.
A diamond that stays in a locker is doing nothing. Taking the mining premium out of the price changes what the piece is for — it can be worn on a Tuesday. That is the argument for lab-grown stones we actually believe: not that they are a cheaper substitute, but that they let good jewellery be part of an ordinary week.
Plainly
Resale markets for lab-grown diamonds are young and production costs are still falling. Nobody knows what one will be worth in ten years. We publish an exchange and return policy instead, because a policy is a thing we can be held to and a forecast is not.
Growing a diamond takes energy, and how much — and from what source — depends on the reactor it came out of. We have not audited that, so we are not going to market on it. If that changes, and we can show the working, we will say so.
Published Indian comparisons run from roughly 30% to 90% less than a mined stone of the same specification. The real figure depends on carat weight, colour, clarity and which laboratory graded it. A headline number would be true of exactly one stone, so we will show you the two specifications side by side instead.
Where we are
Three ways to see us. In person in Gurugram, at a time we agree. At your home, anywhere across Delhi NCR, which is what most people choose when a ring is a surprise. Or over a video call, which is enough to narrow a shortlist even though it is not enough to choose a stone.
The same four commitments apply to every piece, whether it came from the collection or from a sketch on the back of something.
