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.

Iranian Onyx Blocks, Slabs & Finished Products

Iranian Onyx is a translucent natural stone characterized by distinctive veining patterns and structural density. Sourced directly from Iranian quarries, it provides a stable material basis for luxury interiors, backlit feature walls, and specialized architectural applications.

Available Colors and Characteristics

We supply three primary color variants, each selected for consistent structural integrity and pattern quality:

  • Pink Onyx: Defined by warm tones and natural contrast, typically used in interior focal points.

  • White Onyx: Features high light transmittance and a clean aesthetic suitable for minimalist architecture.

  • Green Onyx: Displays pronounced natural veining and depth, frequently specified for decorative paneling.

Supply Formats

Material can be prepared according to project or facility requirements:

  • Raw Blocks: Unprocessed quarry blocks ready for custom cutting at industrial facilities.

  • Cut Slabs: Polished and calibrated slabs ready for immediate installation.

  • Finished Products: Custom-fabricated stone pieces processed to exact project dimensions.

Quality Evidence and Pre-Shipment Inspection

To manage the natural variability of Onyx, every export lot undergoes structural and aesthetic verification before packing. Standard inspection covers color consistency, vein pattern matching, surface polish quality, thickness tolerances, and crack assessment. Physical samples can be provided to establish acceptance criteria prior to commercial commitment.

Our FAQs
Onyx’s higher price reflects both its rarity and the complexity of producing it. Unlike marble, which is quarried in far more locations worldwide, Onyx forms in only a handful of sites through an extremely slow natural process. Its fragility also means higher material loss during extraction and cutting, and the resin reinforcement required on the back of each slab adds to finishing costs. These factors combine to produce a price that accurately reflects the stone’s genuine rarity and quality.
We supply Pink, White, and Green Onyx sourced directly from Iranian quarries.
We provide raw quarry blocks for factory processing, cut slabs for direct architectural use, and custom-finished products based on exact project requirements.
Natural stone inherently varies in color and veining. We manage this through clear lot-specific photography, physical sample approval, and strict sorting during the pre-shipment inspection.
We strongly recommend physical sample approval as part of the evaluation process to align expectations on color, transparency, and veining before a commercial commitment.
