White Onyx: A Complete Guide

White Onyx is a beautiful, high-quality natural stone known for its pure white color, light passability, and smooth appearance. This rare and valuable stone is found mainly in Iran, in places such as Qorveh (Kurdistan) and Kerman, as well as in Italy, which is one of the largest producers. It has a glossy surface, good durability, and a bright finish, making it an excellent choice for interior decoration, walls, floors, and luxury buildings.

What is White Onyx?

White Onyx is a natural stone made mostly of calcium carbonate (99%). It forms when limestone goes through changes under high heat and pressure. This process creates a dense, crystal-like stone that can allow light to pass through, giving it a soft glowing effect.

This stone has been used in luxury buildings, religious sites, and historical buildings for many years. Famous structures like the Taj Mahal and various religious shrines use this stone to create a bright and stylish atmosphere.
