Basalt and diabase which is expensive
Diabase is a good building material polished very beautiful! I personally think that the price of diabase is high
Diabase is a very good building materials, hardness (fresh rock generally 6-7 level), color light green and uniform, polished after the beautiful color, pattern is very nice.
In general, the rock mineral particles are as fine as possible. The basalt is the formation of the role of volcanoes, generally there are pores exist, the color can not be compared with the diabase than the United States, the hardness level is also less than diabase, so that the price of diorite is very normal.
