Stone for stone, a diamond is more expensive than an emerald.
It may not be evil, but it is necessary for life beyond the stage of being a caveman. Come to think of it, even the caveman mined rocks to make stone spearheads. Metals and minerals that are used in everyday life come from mining. The computer you are using to read this contains about 30 substances obtained by mining. It is powered by electricity carried on copper wires (mining) from the powerplant, which probably uses coal or uranium (mining) The food you ate tonight was transported in a metal truck (mining) that traveled on a paved road that was made with crushed stone (mining). If someone did not grow a material, it was, at some point, dug out of the ground.

Crushed stone.....

1 yard of 1" crushed stone
Other names for gravel include crushed stone, rock chips, pebbles, and aggregate.
Aggregate is the general name for a mixture of crushed stone, gravel, and sand.
Crushed stone density is variable ranging from 2.4 - 2.7 Metric Tons per cubic Meter depending on the type of stone, the stone crushing machinery, and how the crushed stone is sorted after crushing.

Crushed stone is mainly used as a construction material for building roads, driveways, and foundations. It is also used in the production of concrete, asphalt, and railroad ballast. Crushed stone is versatile and can be used for various landscaping and decorative purposes as well.
2.7T/m3 (+/- 10%). The above answer is for solid rock, generally not crushed stone. Crushed stone of uniform size has a nominal density of 100 pounds per cubic foot (1.6 Metric Tons per cubic Meter). If the crushed stone is a mixture of various sizes, then the open spaces that would be present in crushed stone of uniform size will be filled somewhat by the smaller sizes, and density increases. Typical effective density here ranges from 120 - 140 pounds per cubic foot (1.9 - 2.2 Metric Tons per cubic Meter). Solid Rock will be close to 150 - 170 pounds per cubic foot (2.4 - 2.7 Metric Tons per cubic Meter). Crushed stone density is variable depending on the type of stone, the stone crushing machinery, and how the crushed stone is sorted after crushing.
In the past most crushed and broken stone has been mined from open quarries. Today, the trend has been more toward underground mining.
