About UsKoin International – the trusted name in Diamond Tenders
Koin International DMCC is a leading international diamond tender house, and one of the top tier tender houses in the UAE’s Dubai Diamond Exchange (DDE).
We provide specialist rough and polished diamond sales, expertise and services to a global client base. We represent suppliers across the board from mines and large scale rough producers, to smaller artisanal diggers. The strategic partnerships we form with our suppliers, along with a broad spectrum client base of over 2,000 approved and pre-qualified buyers, allows us to leverage our expertise to ensure that we match exactly the right goods to the right buyers.
As a leader in the field, Koin has also been one of the first tender houses to introduce lab-grown diamonds to the tender market.
Journey to Success
It has been an incredible and humbling journey, since the first Koin tender in 2015 to one of the leading international diamond tender houses today. This comes with many memorable moments, not least the opportunity to market and sell the 467ct Meya Prosperity—the 29th largest diamond ever found, and the 5th largest in Sierra Leone. We’ve achieved this by emphasising personal relationships, and honing our systems to meet the needs of our large network of clients. These factors combined with a passion and love for the industry and a deep belief in the need to evolve, are key driving forces behind Koin’s success today.
