The Specific Gravity of Gems function provides the specific gravity of various gems and minerals. Note that the specific gravity for Tanzanite is more specifically for Tanzanite (ziosite).
INSTRUCTIONS: Enter the following:
Specific Gravity of Gem (SG): The calculator returns the specific gravity.
is the ratio of the density of a substance to the density of a reference substance. For gems the reference substance is water. Therefore, the formula for is:
SG = `gamma / (gamma_W)`
