From Mumbai to Delhi: House of Quadri Brings Its Signature Diamond Experience to the Capital
“House of Quadri expands to Delhi, offering immersive experiences and showcasing iconic lab-grown diamond collections Allure and Ellipses, while championing ethical luxury and personalized craftsmanship.”
After the success of its flagship in Mumbai’s heritage district of Fort, House of Quadri unveils its second retail destination in Delhi, marking a significant milestone in the brand’s journey. Known for redefining fine jewellery through its philosophy of “Luxury as a Habit,” the brand continues to champion the beauty, accessibility, and sustainability of lab-grown diamonds.
The Delhi store introduces patrons to House of Quadri’s most iconic design narratives, offering an immersive experience that celebrates craftsmanship, innovation, and timeless appeal. At its heart lie two exquisite edits, Allure and Ellipses, each reflecting the brand’s signature design language. The Allure collection reinterprets the marquise and pear cuts with a bold, modern sensibility. Traditionally associated with grace and sophistication, these forms are now imagined through sculptural silhouettes that fuse drama with delicacy. The elongated marquise and graceful pear are transformed into contemporary expressions of individuality, embodying the balance between strength and elegance that defines House of Quadri’s aesthetic.



In contrast, Ellipses celebrates the oval cut, geometry’s most elegant rebellion, with jewels that exude quiet sophistication. The collection highlights the flattering fluidity of the oval shape, crafted to enhance the natural grace of the hand. Through thoughtful detailing, subtle elongations, and refined symmetry, each piece captures the brand’s commitment to effortless modernity and timeless allure.
Beyond its curated collections, House of Quadri continues to celebrate personal expression through bespoke creations. Clients are invited to collaborate with the brand’s artisans to design rings that reflect their individuality whether marquise, oval, round, or an unconventional silhouette each transformed into an heirloom that carries personal meaning.

“For us, Delhi was never about replication, but evolution,” says Vaibhav Karnavat, Founder & CEO of House of Quadri. “We wanted to bring our most iconic collections to a city that deeply appreciates craftsmanship and culture. This store represents our ongoing journey, a celebration of modern design, ethical luxury, and everyday elegance.”
More than just an expansion, the Delhi store embodies the evolution of thought and forms a space where diamonds are not reserved for occasions but designed to be lived with. It invites every visitor to experience fine jewellery as an extension of self-wearable art that celebrates individuality, emotion, and the quiet luxury of everyday life.
