Brown Onyx marble is a natural stone revered the world over for its rich, earthy tones and beautiful, patterning. Within each slab you will find hues ranging from coffee browns to honey golds, as well as ivory white ribbons. These appear in thick, striped bands and pools against a cloudy, Jovian-like base stone.
As a sedimentary material, Brown Onyx has a fine-grained structure formed due to spring water gradually depositing minerals deep in the Earth’s crust. Over millions of years, this forms Onyx composed mainly of calcite and travertine marble with various minerals giving it its distinctive tones.
The marble is quarried in several locations with some of the most prized Brown Onyx originating in Western Iran.
