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

Iranian Onyx Stone

Iranian Natural Stone Supply and Export

Iran’s geological diversity supports a broad range of architectural and decorative stones. Coolak coordinates sourcing for importers, stone processors and project buyers, covering quarry selection, grade review, dimensions, finish and export packaging. This category helps buyers compare the principal stone families before moving to a specific product.

The website currently presents the Iranian onyx category and the detailed onyx blocks and slabs product page. Verified granite, travertine and other natural-stone products can be added to this category as the portfolio expands.

How to Select Stone for a Project

Selection should reflect interior or exterior use, climate, traffic, colour range, pattern consistency, thickness, dimensions and surface finish. Natural variation occurs between quarries, blocks and slabs, so samples, current-lot images, acceptance criteria and inspection procedures should be agreed before contract.

For a detailed sourcing, inspection and shipping checklist, see our Iran onyx supplier guide.
