Granite:
1. Granite is hard in texture, uniform in structure, beautiful in color, and comfortable to be weathered. Its color and luster can be maintained for decades or even hundreds of years. It can withstand very severe weather.
2. Granite has a lower cost. From the perspective of value, granite is more suitable for tombstone making.
Marble:
1, the marble is relatively soft, easy to scratches. Many grains, easy to weathering. Not suitable for a long time outdoors.
2. The inside of the marble is rich in calcium carbonate, which is easy to be corroded and weathered, making the surface lose luster quickly.
Therefore, after years of experimentation and research, granite is more suitable for tombstones.
