May 23, 2011Best Answer The volume of the corundum is the same as the volume of the water displaced. Water is usually defined as having a specific gravity of 1, which means that one ounce of water displaces one unit of volume So, specific gravity = weight of one unit of corundum /weight of one unit of water so

Corundum New World Encyclopedia

Corundum is a crystalline form of aluminum oxide and a rock-forming mineral.It is naturally clear but can have different colors when impurities are present. It is superior in hardness and therefore useful as an abrasive.In addition, transparent, colored specimens are valued as gems.These gemstones are called ruby, if red, or sapphires, for colors other than red.
