IGI-Certified Diamonds

Unlike most jewellers who skip certification on small stones, every Black Mango tennis bracelet and necklace carries full IGI (International Gemological Institute) certification. That means each diamond—no matter how delicate—has been independently verified for quality, authenticity, and fire. It’s your guarantee of uncompromising standards, unmatched sparkle, and confidence that shines as brightly as the jewelry itself.

Founder's Story

I once lost my 1.2-carat wedding ring — a painful moment that made me question what diamonds really meant in my life. At first, I thought I could never replace it. But instead of walking away from diamonds, I found myself drawn into a new way of seeing them.

That’s when I discovered lab-grown diamonds — real in every way, but free from the weight of guilt. Guilt in the larger sense, knowing the painful history of conflict stones and the damage of traditional mining. And guilt in the personal sense too, the fear of owning something so expensive that it stayed locked away for “special occasions” instead of being part of daily life. Lab-grown diamonds lifted both burdens. They made diamonds not only ethical, but also accessible — something I could enjoy freely, every day.

From that moment, I wanted to share this possibility with others. At Black Mango, our team is dedicated to sourcing only the finest lab-grown diamonds from around the world — certified, carefully selected, and crafted with integrity. We believe diamonds should carry more than beauty. They should carry trust, conscience, and a place in your everyday story.
