Quality Review Before Purchase

Colour, translucency, vein pattern, pores and natural fissures vary by selection and lot. Catalogue images alone are not sufficient for approval. Samples, current-lot photos or video, the accepted colour range, resin treatment and rejection criteria should be documented. Buyers comparing onyx with other materials can return to the Iranian natural stone category.

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