About us

Our family, which has been engaged in the trade of precious stones and metals for many years, entered the diamond sector in 2017 with the Diagen Diamond brand. After opening our first branch in Cologne, Germany, we started establishing stands in many jewelry stores across Germany and began granting franchises. During this process, we signed a significant agreement with Gençay Kuyumculuk for the distribution in Turkey.

At Diagen Diamond, we not only offer high-quality products but also strive for perfection. The golden ratio used in our brand’s logo is a symbol of our quest for this perfection.

Our extensive experience in precious stones and metals is combined with our commitment to offering the highest quality to each of our customers. Diagen Diamond is not just a jewelry brand, but an expression of a passion that brings together elegance and fine craftsmanship.
