Specific gravity is measured by the relative comparison weight of water.
For example, if a gemstone has a specific gravity of 3.6, than that mineral is 3.6 times heavier than water. For example, Elie Ruby is not a type of ruby, but rather pyrope garnet. ALSO SEE Hyperlinks to other reference material. Copyright 1997 - 1999 Hershel Friedman, all rights reserved.
