90 Million Years in the Making
The Tethys Sea Created It.
Diamond Stone Delivers It.
Oman's Semail Ophiolite is one of earth's greatest geological wonders — an ancient seabed thrust skyward by tectonic forces, transformed by heat and pressure into stone of extraordinary beauty and density.
Each Diamond Stone marble carries this geological provenance within it. The veins you see are a record of real tectonic events, frozen in time. No two slabs have ever been — or ever will be — identical.
