At Coolak, we believe that successful transactions are built on trust, transparency, and informed decision-making. This belief is reflected in several principles that guide our work: Transparency throughout the commercial process Careful verification before presenting opportunities Risk reduction before problems arise Practical and executable transaction structures Long-term business relationships rather than short-term gains These principles are not marketing statements. They are the standards by which we evaluate our own decisions.

Onyx Stone

Natural stone remains one of the most authentic and enduring building materials ever used. Since humans first shaped tools from rock, stone has been with us — and even today, surrounded by thousands of advanced synthetics, it still holds its ground.

Why? Because nothing else offers that rare combination of beauty, strength, and longevity. A marble floor can last a century. A granite facade withstands rain, frost, and heat without flinching. And a travertine staircase only grows more compelling with age.

Iran is one of the richest stone-producing countries in the world. From the veined marbles of Dehbid to the black granites of Nehbandan, from the creamy travertines of Abadeh to the translucent green onyx — this country yields a remarkably diverse range of high-quality stone that has been featured in major projects worldwide.

At Coolak, we supply Iranian natural stone directly to global markets. From quarry selection to loading and export — all handled to international standards with full transparency.
