Onyx

Onyx is a type of metam or phic stone that f or ms due to changes in pressure and temperature in limestone. This stone is one of the most popular and luxurious natural stones in the construction industry, known f or its beauty, col or variety, and distinct transparency. Here, we will explain m or e comprehensively the features of onyx, how it f or ms, its various types, and its applications.

As a metam or phic stone, onyx f or ms from limestone or dolomite under high pressure and temperature deep beneath the Earth’s surface. This physical and chemical transf or mation causes limestone to convert   into onyx's crystalline structure. The time and specific environmental conditions during this process give each piece of onyx its unique characteristics.
