Since the 1950s, Legacy Diamonds and Gemstones has stood as India's preeminent diamond house — born from a vision to bring the world's most exceptional stones to the world's most discerning collectors.
Legacy Diamonds and Gemstones was born in post-independence India, during a period of national renaissance and ambition. Our founders — Vijay DN Si Nha and Sachin Anand Si Nha — understood that diamonds were more than precious stones. They were symbols of enduring value, living legacies passed from one generation to the next.
From a single workshop in Mumbai, they built relationships with the world's most respected diamond cutters, graders, and collectors. Every stone was sourced with intention, cut with mastery, and certified for permanence.
Today, that founding vision endures — refined by three generations, expanded across continents, and elevated by the world's most rigorous gemological standards. What began as a promise has grown into a legacy.
Three principles that have shaped every stone we source, every relationship we build, every legacy we help create.
Every diamond we offer is selected for extraordinary optical performance. We seek stones of uncompromising brilliance — where light does not merely pass through, but transforms into something transcendent. Our gemologists evaluate each stone against the highest standards of cut, clarity, colour, and carat, ensuring that what you receive is not simply a diamond, but a captured moment of pure light.
From the sourcing of raw stones to the setting of the final piece, every aspect of our craft demands artistic excellence. We collaborate with master craftspeople whose techniques have been refined across generations — ensuring that each Legacy creation is a masterpiece in its own right. Our bespoke commissions honour the vision of the collector while elevating it through generations of accumulated skill.
Trust is the foundation upon which Legacy was built. For over seven decades, we have maintained absolute transparency in every transaction — providing GIA certification for every stone, complete provenance documentation, and absolute discretion in every client relationship. Our reputation, built across three generations and four continents, is the testament to a promise we have never once broken.
In the decade following Indian independence, Vijay DN Si Nha and Sachin Anand Si Nha founded Legacy Diamonds with a singular conviction: that India's ancient relationship with diamonds deserved a modern, world-class home.
Operating from Mumbai — the commercial heart of a newly independent nation — they established relationships with the world's most respected cutting centres in Antwerp and Amsterdam, building a supply network founded on quality, integrity, and personal trust.
From the very beginning, certification was paramount. Every stone passed through rigorous grading before being offered to clients. This uncompromising standard became the cornerstone of the Legacy reputation.
The second generation inherited not just a business, but a reputation — and proceeded to take it to the world. Expanding into Europe, the United States, and the Middle East, Legacy Diamonds established itself as a trusted partner for luxury brands, royal households, and elite investors across four continents.
Partnerships forged in this era brought Legacy stones to collections that would become the stuff of legend — worn at state occasions, displayed in private galleries, held as generational investments by families of profound wealth and discernment.
The New York office was established during this period, cementing Legacy's position as a truly global diamond house with roots in India and reach across the world.
In 2014, Su Deep Si Nha and Devika Si Nha assumed leadership of Legacy Diamonds, bringing a new generation's values to a storied institution. Their vision: to honour the founding legacy while embracing the demands of a new era — transparent supply chains, ethical sourcing, digital accessibility, and a new generation of global collectors.
Under their stewardship, Legacy has implemented rigorous ethical sourcing protocols, established direct relationships with responsible mining operations, and brought the Legacy experience online — making world-class GIA certified diamonds accessible to collectors across 12 countries and 8 major markets.
The legacy continues — and grows more brilliant with each passing year.
