Diamonds have always been part of my story.

I come from a family with nearly a century of heritage in the diamond trade.

I learned the business from the ground up — from grading diamonds hands-on to working across the global diamond industry.

Today, that experience is shaping Réia Diamonds, a modern jewellery brand I’m building around how a new generation wants to discover, buy, and wear diamonds.

“From my family’s roots in Kota Diamonds to building Réia — understanding the stone before building the brand.”

Building something of my own.

Réia Diamonds

Everyday jewellery, as personal as your story.

Inspired by the modern woman, we built Réia to awaken the queen within her replacing traditional jewellery counters with high-touch consultation studios, in-house 3D CAD rendering, and bespoke craftsmanship for your most meaningful milestones.

Knowing the stone before building the brand.

Technical depth meets bespoke precision.

01
Ground-Up Gemology

Ground-Up Gemology

My product judgment is grounded in hands-on diamond grading at S. Vinodkumar and my JK Diamond Institute credential — mastering the physics, 4Cs, and optical brilliance of every stone.

02
3D CAD & Resin Prototyping

3D CAD & Resin Prototyping

We reject standard stock-and-sell. For every bespoke piece, our studio produces 3D CAD renders and photorealistic resin prototypes (RPT) so you can try on your heirloom before a single stone is set.

Accessible Structural Luxury

Accessible Structural Luxury

We are pioneering India’s structural shift toward ethical, lab-grown diamonds — chemically and optically identical to mined stones, crafted without artificial scarcity.

How I got here.

A foundation that keeps moving.

My Perspectives & Thoughts.

What I think about diamonds, retail, and building.

Consumer Evolution3 min read

The shift from tradition to personal agency.

I believe modern corporate women aren’t waiting for permission or someone else’s timeline to own diamonds. They buy milestone rings and everyday fine pieces to celebrate their own promotions, achievements, and identity.

Category & Sourcing4 min read

Democratising design without artificial scarcity.

To me, the true revolution of lab-grown diamonds isn’t just crystal synthesis — it’s freeing jewellery from artificial supply constraints so clients invest in bespoke artistry and benchwork rather than inflated margins.

Retail Architecture3 min read

Why physical consultation studios outperform transactional ecommerce.

Diamonds are deeply emotional. In building Réia, replacing glass counters with intimate living-room studios and resin prototype try-ons turned an intimidating purchase into an empowering design journey.

Let’s build what comes next.

Hit me up at 3am and I’ll be ready to explore a new corner of the globe — or talk your ear off about what we’re building next.
