Crystal
Crystal stone, known in Iran as sang-e chini, is chosen for slabs, floors, stairs, wall cladding and, in some projects, façades for its light backgrounds and varied veining. The products on this page are Iranian crystal stones with different patterns and grades, and should be compared on samples or photos of the batch that can be delivered. Crystal price does not depend on the product name alone: whiteness or background colour, regularity of the veins, slab soundness, grade, dimensions, thickness, polished or honed quality and order quantity all affect it. For crystal slabs, pattern continuity and sound dimensions matter; for floors and stairs, thickness, finish and installation conditions also need to be defined. A floor price per square metre is shown for selected products, and the final price is given once order details and deliverable stock are set. In a slab project, place full photos of the pieces side by side to decide vein direction and whether book-matching or a continuous pattern is possible. For floors and stairs, view the background colour under the light of the installation site, and agree thickness, surface finish and installation method with the installer before ordering. To buy crystal stone, send the stone name, slab or tile form, dimensions, area, thickness, finish and project city.

Standard technical requirements: ASTM C503
| Property | Minimum requirement | Test method |
|---|---|---|
| Absorption by weight | ≤ 0.20 % | ASTM C97 |
| Density (calcite marble) | ≥ 2595 kg/m³ | ASTM C97 |
| Density (dolomite marble) | ≥ 2800 kg/m³ | ASTM C97 |
| Compressive strength | ≥ 52 MPa | ASTM C170 |
| Modulus of rupture | ≥ 7 MPa | ASTM C99 |
| Flexural strength | ≥ 7 MPa | ASTM C880 |
| Abrasion resistance | ≥ 10 Ha | ASTM C241 / C1353 |
These are the minimum physical requirements of ASTM C503 for building stone, not test results for this product. You can ask for the laboratory test report of the batch you order. Source: ASTM C503
