When natural granite, quartzite, and marble are all formed deep in the earth’s crust, onyx comes into being right on the surface. Onyx stone is created from spring water or groundwater that has a good amount of calcite dissolved in it. When this water emerges at the mouth of a spring, the minerals precipitate out and build a crust of calcite crystals. Over a period of time, more water flows by and more minerals settle out. The variations between the layers are caused by differences in the water flow rate and small amounts of impurities. In its most pure state calcite is white or clear, but it’s easily tinted by minor amounts of other minerals.
Onyx can also form inside caves or in other openings in bedrock. Veins of banded calcite can be found in fractured limestone, or even in volcanic rocks. Basically, beautiful formations of crystals can be created anywhere that mineral-laden groundwater flows. All it takes is the happenstance to discover the underground cache.
Travertine is formed in the same manner as onyx. The main difference between travertine and onyx is that travertine has a porous, lace-like texture while onyx is smooth and non-porous. Aside from that, the two stones are similar.
