In today's society, more and more people are beginning to pay attention to the decoration of the living environment, and most people choose to use marble and granite when decorating their houses. After all, both are high-grade finishing materials. But what is the difference between granite and marble? To put it simply, those with texture are called marble, and those with spots are called granite. Natural stone is roughly divided into three categories, marble, while granite is a kind of igneous rock, and sedimentary rock, which is not too deep in the ground. Here is a brief description of the difference between granite and marble.

一、Granite
The pattern of granite is spotted and the pattern is relatively simple, without obvious pattern forming. Most of them are used outdoors, and their advantages are sturdy and durable, not easy to be damaged, and will not be stained. The production standard of natural granite building board is made according to the ordinary board, but the board is divided into three grades of excellent product (A), first-class product (B), and qualified product (C). Its specification size deviation, straightness tolerance, angle tolerance, and appearance quality are measured by grades.

The mineral composition and structure of granite depend on its quality. High-quality granite will have fine and uniform crystals, less mica and more quartz, and does not contain pyrite. Granite is not easy to be weathered and deteriorated, and its appearance and color can be maintained for more than a hundred years.
　　
The price of granite ranges from tens of yuan to several hundred yuan. The rough surface is cheaper, and the smooth surface is more expensive.

二、Marble
 Marble is a type of stone, and now many people choose marble for floor decoration. Because marble is an artistic stone, its texture is smooth and delicate, the pattern changes are rich, the line patterns are smooth and freehand, the color changes are rich, and it has charming patterns like landscape paintings. Therefore, in some high-end places, the floor will be covered with marble, and the marble is in Patterns are more comprehensive in production and processing, but the biggest drawback is that it is many times more expensive than granite.

The price of marble ranges from hundreds of yuan to several thousand yuan. Due to different origins and different quality prices, there are very big differences. Therefore, it can be seen from the features, functions, and price differences that the difference between the two is still very obvious.
