From Mine to Masterpiece
Our Story
Is where rarity meets refinement. ‘TaTe’ meaning ‘father’ and ‘leader’, reflects our mission: to lead with integrity and mission in the world of fine jewelry.
Born in Namibia — a land celebrated for producing 95% gem-quality diamonds, the highest standard in the world — our story begins with one of nature’s most precious and hard-to-get treasures. But rarity alone isn’t enough. At TaTe Diamonds, we elevate what the earth gives it through exceptional craftsmanship and a refined aesthetic, turning each diamond into a statement of timeless luxury.
Every TaTe Diamonds creation is crafted to mark life’s defining moments with timeless elegance and profound significance.
Our Mission
We are dedicated to creating extraordinary jewelry that
transcends trends and celebrates the stories that define us.
With a steadfast commitment to sustainability, transparency,
and craftsmanship, we offer diamonds as rare as your love
and as exceptional as your journey.
Guided by the Kimberley Process, we ensure every diamond is
ethically sourced and conflict-free, giving you the confidence
that your jewelry reflects both unparalleled beauty.
And uncompromising values. We believe in making luxury
personal, accessible, and deeply meaningful.
Our Mission
TaTe Diamonds brings you the world's only true mine-to-finger diamonds, ensuring unmatched traceability, quality, and
exclusivity. Beginning in Namibia's pristine landscapes, our diamonds are responsibly recovered from the ocean floor and
land through sustainable practices led by Debmarine Namibia and NamDeb.
From the hands of Namibian artisans to our flagship Buckhead Atlanta showroom, every GIA-graded diamond is mined, cut,
and polished with care, then transformed into a masterpiece of timeless sophistication.
By eliminating the traditional 15-step supply chain, we deliver diamonds of extraordinary rarity directly to you, ensuring a
seamless blend of heritage, craftsmanship, and contemporary luxury. With TaTe Diamonds, you don't just wear jewelry—you
wear a legacy.
Guided by the Kimberley Process, we ensure every diamond is ethically sourced and conflict-free, giving you the confidence that your jewelry reflects both unparalleled beauty.And uncompromising values. We believe in making luxury personal, accessible, and deeply meaningful.

Giving back
True beauty shines brightest when it uplifts others. Here at Tate Diamonds, our mission goes beyond creating exceptional jewelry. We’re all about using our craft to inspire hope, dignity, and opportunity in the communities we serve.
Empowering Women Worldwide
We are honoured to partner with the Global Fund for Widows, a United Nations–affiliated organisation dedicated to uplifting widows and female heads of households through entrepreneurship, microfinance, and vocational training. Through this collaboration, TaTe Diamonds contributes $250 from every jewelry purchase above $1,000 to help fund life-changing programs that create sustainable livelihoods and independence for women across Africa, the Americas, and beyond. As a Bronze Sponsor of the 2025 Global Fund for Widows Annual Awards Gala in New York, we proudly stand beside global leaders advancing the cause of women’s economic empowerment and dignity.
Supporting Orphanages and Children’s Homes
Since 2018, TaTe Diamonds has worked closely with the Megameno Orphanage and The Dolam Children’s Home, helping provide children with access to shelter, care, and education. Our commitment ensures that every child touched by these programs feels valued, safe, and supported as they grow into confident, hopeful young adults.
Honouring Elders in Our Community
Each December, we host a Christmas luncheon for the elders of Donkerhoek, a historic community in Katutura. The event is a celebration of their wisdom, resilience, and the generations they continue to inspire. It’s one of our most cherished traditions where we spend a moment to give thanks, share joy, and reconnect with the roots of compassion that define who we are.
